Retired Penn professor arrested for blocking Uber Eats robot

> Marvin, 78, said she's not sure how many times she's blocked the path of these robots, which hit the streets of Philadelphia in March. The University of Pennsylvania professor emeritus has made a practice of it to protest "corporations that displace human delivery workers in order to enrich their own bottom line." Her past encounters have circulated online. The Wednesday incident was the first time, however, that the police got involved.

> Officers approached Marvin after she'd been there "quite a long time," she said. They asked her to step aside and let the robot complete its delivery. When she repeatedly refused, they arrested her for disorderly conduct.

Good. I want delivery robots to be able to operate in public, I don't want people like Marvin to be blocking them because they disapprove of the concept of delivery robots or think it's bad that they're displacing human jobs, and I think that a disorderly conduct arrest is an eminently reasonable response from the criminal justice system.

> Marvin, who plans to contest the charge on the grounds of her First Amendment right to protest, has been undeterred by the arrest. She plans to continue blocking Uber Eats robots and chatting with curious passersby who ask what she's doing.

The first amendment doesn't and shouldn't protect interfering with reasonable delivery robot use of the public streets; indeed the law should protect the rights of operators of delivery robots to have their robots deliver items to customers without interference. The criminal justice system should absolutely incarcerate her if she publicly intends to continue interfering with delivery robots.

1A says she is free to protest human workers by getting in their way in public. Do you think picket lines are illegal? Why is this different because they're robots?
gravypod•10m ago
> 1A says she is free to protest human workers by getting in their way in public.

I am not a lawyer but I don't know if the first amendment allows you to block access from others to things. Some things similar to this are covered in this ACLU blog post: https://www.aclu-il.org/news/when-else-can-government-regula....

mlyle•7m ago
> Do you think picket lines are illegal?

Picket lines that actually block other people from crossing instead of trying to persuade them not to? Yes. Use of threats, physically blocking, or just general impediment? Yes.

Not only does it violate state law (e.g. obstruction of free movement, interference with a business open to the public, false imprisonment, and assault are all offenses here in California depending on the facts), but it also violates NLRA rules.

(e.g. a recent labor case found repeated 1 to 4 minute "inadvertent" blockages unlawful -- https://www.laborrelationslawinsider.com/2018/02/the-nlrb-si...)

The Moscone Act that recognizes picketing federally also makes clear that this is not OK.

> It is not the intent of this section to permit conduct that is unlawful including breach of the peace, disorderly conduct, the unlawful blocking of access or egress to premises where a labor dispute exists, or other similar unlawful activity.

good for her. nonviolent obstruction of a commercial endeavor she opposes, much like a sit-in. whether you agree with her perspective or not I think it is important to support her ability to protest in this way, though (as she is well aware) it may come with consequences.

What if the robot was delivering insulin? Would it be such a noble act then?

Not saying I disagree in principle, but the protestor assumes a lot of knowledge.

You're assuming you know what it's carrying. For that matter, the food may be medically urgent for this person.

I do this whenever possible. I honestly don't understand why these aren't constantly vandalized. I just wanna peacefully protest them like this ex prof, but there's plenty of folks out there who'd like a free meal that's rolling by in a beach cooler that stops when you stand in its way.

Apparently these robots are classified as pedestrians in Philly. This is a huge mistake, they should be the same as bicycles
Human-Cabbage•22m ago
I don’t agree with her stance, but it’s absurd to call standing in the sidewalk “disorderly conduct.” I hope the judge sees it that way too and dismisses the charge.
mlyle•20m ago
Standing in the sidewalk, and refusing to get out of the way of another sidewalk user.

I mean, I could block a wheelchair user by standing in a cut-out, too. Is that OK?

I'm sympathetic to her cause; these robots are a waste of space, poorly designed and behaved - the ultimate bad neighbor as you walk down the street. I do believe that delivery robots are inevitable, and I welcome them when they come - but these are not that, and the combination of fees and fines should keep the current model off the streets.
alamortsubite•18m ago
Now that the cops have helped her get the message out, by arresting her, would a better approach be to go up to the robot, say "Hi, I'm giving these out for free today, if you don't want one, let me know," put a bag over the camera pod, and leave? It seems like her time is too valuable to waste actually blocking the robot.
jrochkind1•14m ago
I think that actually would be much more likely to result in a charge that would be harder to defend against, by intentionally interfering with someone else's property. Computer programmers are the only ones that think a charade where you pretend like you might think the robot can respond and say "no thanks" (and weren't really giving them out for free to anyone else) is a legal defense. The law does not work that way.
bonoboTP•17m ago
These things should not be allowed to use sidewalks. They are a disturbance and annoyance taking space away from humans walking, chatting, etc.

I don't think that saving delivery jobs is the main issue, these jobs didn't even exist a few years ago and their working conditions are anyway quite bad. It's a bigger social question why deliveries are getting so common nowadays across many countries including also different parts of Europe. I already find delivery scooters unseemly and they often drive recklessly. Ramping up this stuff even more will just lead to more social isolation, and with that conflict and generally low-trust societies.

I wonder if there is some kind of city tax on these robots. You certainly shouldn't be allowed to just put an unlimited number of these things on the sidewalks and push the negative externalities on everyone else. Same way you need permits for drones, which are also a visual pollution and potential constant privacy invasion. Cars on the road are already taxed, not sure about these.

gvfsa•13m ago
Really you can't see why getting stuff delivered to your door is popular, or is this a rhetorical question
swatcoder•7m ago
I don't think they're saying they're confused about the psyche of individual people electing for delivery.

The "social question" to explore is about how so many people collectively came to see leaving the house, interacting with others humans, and setting aside work or idle distractions as bad things to be bought off with cash that we had to work to earn.

We know that people like delivery and we know that people don't like the alternatives I mention above, but that wasn't always the case and it's probably worth slowing down to think about what change and whether that might correlate with other concerns.

It is fantastic that someone is defending the noble long-standing profession of Door Dash driver. Its long history and entry path for long careers in delivery driving are fundamental to the strong middle class of this country.

Let's continue this process and protest the use of other automation like commercial dishwashers and street sweeping trucks. After all, they are displacing vitally important jobs.

People have been delivering pizza since... well since pizza was invented probably.

ckwalsh•10m ago
If a new part of this arrest is that the robots are considered to be pedestrians, I wonder what the police would do if the professor replayed the exact same circumstances with a friend in place of the robot?

Decide one of them is delivering something, run into each other at the exact same spot, and call the police to resolve it?

bradgranath•17m ago

crote•19m ago
And what about the person's right to continue without being obstructed?

It's a standoff. She's literally just standing there. She doesn't move out of her way to let the robot pass - but neither does the robot move to let her pass!

So why should she be the only one arrested and incarcerated? Why not arrest the robot for the same crime?

Sidewalks are for humans to walk on, not dedicated travel corridors for commercial robots. If those robots can't play nice and yield to pedestrians, then they don't belong on the sidewalk.

JuniperMesos•13m ago
Because the robot is operating normally and not particularly trying to obstruct her or any other person; whereas she is deliberately interfering with the robot because she has a political grievance against delivery robots and thinks it is good to interfere with their normal operation. The law should absolutely make a distinction between those two things when regulating what sorts of physical movement on the public street constitute a crime.
Dusseldorf•16m ago
The robot was absolutely free to go around her, I truly don't see how what she did was illegal. The next time my kids are out doing sidewalk chalk and the mail carrier walks by, should the kids be arrested for obstructing mail delivery?
JuniperMesos•10m ago
If your kids are making a point of getting out their sidewalk chalk to block the way of the mail carrier every time they see one, because they have a political grievance against the post office and want to do everything in their power to interfere with mail delivery, then yes they should be arrested for this. This is quite possibly already a federal crime, in fact.

I'll bet the person protesting would be of the opinion that it should be delivered by a person regardless of what it was.

Regardless there is a stark difference between medication, which is necessary, and hot prepared meals, which are a luxury.

nanolith•18m ago
I'd say that this would bring up a bigger issue: why would Uber Eats be in the business of using robot couriers to deliver vital medications? Sandwiches or non-essential goods? Sure, I can understand this maybe, bracketing societal issues that these machines represent.

Prescription medications are controlled. If this robot is damaged or destroyed, the patient may not get their insulin at all without further authorization from their doctor or their insurance company. Those logistical issues are much thornier than a retired professor blocking a delivery robot.

popularrecluse•14m ago
I think you're missing my point. It's not that it's an Uber eats robot today.

But also diabetic hypoglycemia is a thing too, which could be the case for the person ordering. For the sake of argument.

antonvs•17m ago
The protestor assumes nothing more than that these are Uber Eats robots. Getting your Big Mac without moving your ass off the couch doesn't have quite the same moral status as having insulin delivered.

If you need insulin for emergency purposes, call fucking 911, please for the love of god, don't manage your medical emergencies with app based delivery couriers.

swatcoder•13m ago
Ethical questions like this are a lot easier to discuss if you take for granted that people are acting in good faith.

If you truly cared that much about Amazon and truly felt library participation was so heinous that it ought be obstructed, I think a lot of people would be very skeptical and a lot of people would disagree with that perspective, but yes, those of us who believed you were acting earnestly would indeed appreciate you standing up for your principles in a way that was impactful but not violent.

There's less skepticism of sincerity here and more agreement with the fundamental concern here, but the respect for principle and action covers both, yes.

II2II•6m ago
It's civil disobedience, at least once she refused to step aside when told to do so by the police officer. (I don't know if she was breaking the law by obstructing the robot.) So yeah, I would say there is nothing inherently wrong with you obstructing the entry of the local library -- provided you are willing to be peacefully arrested.

That doesn't mean that I agree with your right to obstruct entry into the library, nor does it mean that I agree with your reasons for blocking entry to the library. I also suspect that the courts would reject your reasoning.

tptacek•20m ago
Part of the idea of protesting like this is to elicit arrest. That's what civil disobedience is. It's not a coherent protest strategy if you factor enforcement out!
crote•11m ago
Just because something is physically on the sidewalk doesn't mean it is a "sidewalk user".

If you ask me that thing is an autonomous motor vehicle, and as such belongs on the road and its use of the sidewalk is illegal. Just like it would be if its larger Waymo cousin tried to drive there.

Besides, that robot is also blocking and refusing to go out of the way of the human. There are no laws regulating who has to yield on a sidewalk, so good luck figuring our which one is in the wrong.

A delivery robot has much fewer externalities than your typical delivery person. In a lot of big cities, the person delivering your order will typically be using an illegal e-bike or scooter, flagrantly disobeying traffic laws, and completely uninsured. Oh and good luck enforcing any judgements on them, since they look nothing like the ID used to register for the app.

Is it customary to tip these delivery devices?
