I am bemused every time I use Uber and the car has some flush-mounted door handle that I have to figure out. When exiting the car and closing the door, I end up leaving fingerprints I would not have left if the handle had been designed by someone who had been in a car before.
jjtheblunt•1h ago
agreed on fingerprints, though i bet the rationale is coefficient of drag, not lack of experience with various door handle designs.

in the article, it shows a Magna-Steyr handle on a Mercedes Gelaendewagen, which looks like those on the Ineos Grenadier, and not very different than the ones that Ford uses on various trucks.

that contrasts with those on Audi and BMW evs, for examples i see often, where the CoD is a stated spec for ev shoppers, and the handles have motion to them, but are flush (but not Tesla vanishingly flush). Weirdly, some Porsches (intimately related to Audi...just read the shared parts) use flush handles and some the protruding handles with an actual handle.

i admittedly pay an unusual amount of attention to car componentry, sort of a hobby really.

AlotOfReading•1h ago
The additional drag is negligible. People have been producing "racing doors" with handles for decades. They focus on cutting all the other features of the door like weight and mechanical complexity instead. It's an even more irrelevant consideration for consumers, who could save far more fuel by changing how they drive.

Flush handles exist as brand differentiators. They're a "futuristic" feel-good feature that consumers want, like engine noise, tablets, and colorful dashboards.

> It's an even more irrelevant consideration for consumers, who could save far more fuel by changing how they drive.

These are not in conflict. The energy you save from drag stacks with the energy you save from "learning how to drive".

hshdhdhj4444•24m ago
Yeah, but making opening doors a puzzle to solve is an incredibly terrible trade off.

And that’s before we consider the other aspects of these door handle designs that make the cars a death trap.

kube-system•17m ago
They add a tiny bit to the efficiency and/or range, they look cool (e.g. serve a gee-whiz marketing purpose), and safety evaluations in the markets where they still exist don't penalize them -- up until now they've had very little against them.

Maybe as legal and reputational backlash spreads the pros will not outweigh the cons. But someone designing a car a decade ago, marketed towards early adopter types, would have had no reason not to.

And I say this as someone who hates these handles designs personally.

kube-system•27m ago
All of the things you mention are considerations that every automaker considers. Product design engineering is simply an exercise in weighting those factors, among many others.
WalterBright•21m ago
People who race stock cars will even dip body panels into acid to make the panels thinner. Anything to reduce weight!

Those that care about fingerprints on their car seem like they're different people from those that drive for Uber.

https://www.bbc.co.uk/news/articles/cp37g5nxe3lo

> It comes as EVs are facing scrutiny from safety watchdogs around the world after a number of deadly incidents, including two fatal crashes in China involving Xiaomi EVs in which power failures were suspected to have prevented doors from being opened.

You had one job, door handles... but being made sleek and sexy and unlike normal door handles also made you a fucking liability.

People wonder "Why is there a law for this stupid thing, it's a regulatory hassle", and yet time and time again it comes around there was at least some partially legitimate reason said rule exists.

Simply put vehicles are at the point where we need a rule that says "The doors can be unlocked and open if the battery is dead" Full stop, no ifs, ands, or buts.

cucumber3732842•1h ago
It is not the government's job to enumerate every specific brand of stupid design that may be harmful multiplied by every class of product nor should it be.

If you want to do that stuff, do it with a performance test or criteria, not with stupid whack-a-mole rules. And don't think that weasel wording the test to the same effect is any better. If you want to do this the not stupid way you need to actually do the hard work and figure out what the over-arching general case performance characteristics need to be.

With better styling cues and design that make it obvious how to use the Tesla handles (and all the degrees of copycats) it wouldn't be an issue. But that isn't the kind of sleek sext angular bullshit modern car designers like so it never got made and here we are.

csours•1h ago
Game it out - if you issue guidelines, people abuse them, then government agencies get in trouble (isn't it your job to stop this kind of thing?), so government agencies issue strict rules.

Bureaucracies have many fathers, the society we have is the result of conflict and incentives.

pixl97•39m ago
>enumerate every specific brand of stupid design that may be harmful

As commonly said by the libertarian at heart, right up until the point their loved one gets injured or killed, then they are at the forefront of regulation.

> But that isn't the kind of sleek sext angular bullshit modern car designers like

Who likes safety and security? These features commonly make every day use more difficult. Who needs unblocked fire exits, that takes up too much room in the building. Who needs a common interface for a safety critical device, that removes the 'cool' factor.

One of my unfavorite random car regulations is that as of some time in this millennium, cars sold in the USA may not have required lighting on movable bodywork.

This bans new cars from having clamshell bodywork like that found on classics like the Jaguar E-type and Ford GT40. I suspect it also results in many cars having narrower truck/hatch openings than they would have if they could put mandated lights on the trunk lid or rear hatch.

It's not hard to imagine the partially legitimate reason that on occasion, someone will drive with the trunk open, but do we really need a law about it?

kube-system•22m ago
> It's not hard to imagine the partially legitimate reason that on occasion, someone will drive with the trunk open

No, it's a much more serious and likely reason -- people stopping on a highway at night, getting out, and opening their trunk for some reason (like a spare tire, fluids, etc)?-- then their lights (and the reflectors in the lamp housings) are pointed at the sky.

alistairSH•14m ago
Or, movable bodywork is more prone to be misaligned during normal operation.

Headlights get out of alignment sometimes. I posit that likelihood goes up if the lights are themselves mounted on a hood/door/whatever that can also go out of alignment.

kube-system•3m ago
Alignment is important for headlamps, but I'm not sharing my opinion here -- the FMVSS is pretty clear that for non-headlamp lights, the reason is for visibility:

My dad, in the 1960s, put reflective tape on the rear bumpers.
tbyehl•19m ago
Every safety regulation is written in blood.

That particular blood was probably people stopped at night with the trunk open to access a spare tire or tools. And then there was more blood because sometimes those people forget to leave their lights on, or their lights don't function because the battery has died, so we got more regulation requiring ugly reflectors.

And so on.

WalterBright•19m ago
I don't like electric windows, either. They like to fail in the rain, and are expensive to repair.

Manual windows roll up and down for decade after decade...

Electric door locks are bad, too. After a while, they won't lock or unlock.

boatloof•59m ago
The mechanical flush mount car door handles are because shaping that divot into the steel is much more complicated then punching a hole, and especially aluminum is many times more complicated and expensive. Audi was showing off their technical expertise with creasing aluminum with unlimited money in their bodywork before dieselgate, and that was pretty much peak for car body technology.
