I also like to point out that we had electric powered food delivery services in London from 1932.
bluescrn•33m ago
And the delivery drivers were probably paid more than they are now…

These are ICE and not electric.

> The e-scooters that clutter up pavements may seem like a new thing, but a hundred years ago, there were already people zooming around London on powered scooters.

The problem is that we've given so much space to automobiles that there's no room for anything else (bikes, scooters, etc). Pedestrians have been given a sliver only because drivers need to walk between parking and their destination. This is true even in cities where the majority of people don't even drive!

sheepscreek•1h ago
Probably cause modern logistics, especially last mile logistics, is dependent on trucks/delivery vans/etc. So even though folks in a local area might like to walk around, their groceries won’t make it to the stores and packages won’t get to their homes without a robust road network.

I think Bacerlona hits a good compromise. The city has the concept of a superblock, which is a few city blocks grouped into one calm zone. Most car traffic stays on the streets around the outside, the perimeter of the superblock. Inside, driving is restricted and only at low speeds where allowed, so people and bikes get the space. So deliveries and residents can still but only slowly.

That’s far from the only example - many cities in Asia follow a similar model.

London is edging in that direction with the introduction of "low traffic neighbourhoods". Basically this involves preventing vehicles using them as a through route, by limiting some connections to only emergency vehicles. The problem is that it's also annoying for residents as it means the allowed entry/exit routes aren't necessarily in the direction you need to go. Does Barcelona have a smarter method?
alistairSH•44m ago
Isn’t the presumption that residents walk/bike/transit far more often than drive?
hylaride•13m ago
There is still pushback. I live in Toronto and when central businesses are canvassed about streetscape changes they overwhelmingly are against removing parking, access for cars, etc. They assume that 90% of their customers drive to them, but it turns out that it is closer to 10% for most of them.
ajb•3m ago
That's unevenly distributed. Lots of people in London do walk or use public transport, but you still need many delivery drivers, tradespeople, etc and it doesn't make sense for them all to live outside the city. And people who don't usually drive occasionally need to use a vehicle, and then it's more stressful because you aren't used to having to know where the vehicular entrances are. It's too simplistic to just make provision for the majority and assume that it doesn't matter what the second order effects are.

LTNs and pedestrianised areas are great for criminals on illegal high-powered e-bikes. Purpose-built getaway routes.

Totally. Banning automobiles is usually a bad idea, especially for residential zones. Years ago, I remember seeing a presentation about redeveloping a bad public housing block that was built in the 1960s with no auto-access (the assumption being poor people don't have cars), but it turns out that it meant they couldn't even get pizza.

I dunno... in New York City there are an awful lot of bike lanes now:

https://www.google.com/maps/@40.7355559,-73.9921499,13z/data...

There's still room for a lot more, but plenty of space has been taken away from automobiles precisely for bikes, scooters, etc. It's trending in the right direction. Especially now that bike lanes are increasingly being designed with parking between the bike land and vehicle lanes.

reactordev•17m ago
But this has been true every hundred years or so as technology changes and those that are building infrastructure know nothing else.

2000s : Damn these cars clogging up the road!

1900s : Damn these buggies clogging up the road!

1800s : Damn these carriages clogging up the road!

1700s : Damn these horses clogging up the road!

1600s : Damn these " " " " "

100BC : Damn these romans clogging up the road!

Yes, using AI as per the filename "backgroundexpandedusingai" [0], it seems to be an expanded version of this pic from Wikipedia [1] (but blurrier).
