Yeah we basically figured out door handles and suddenly we’re reinventing them. If it ain’t broke.

- api 3y ago“I want something in this design that will definitely break… let’s add some servo motors!”
- nickpinkston 3y ago"Put a bird on it" for design --> "Put a servo/wireless in it" for hardware...

- sb057 3y agoI'm still skeptical of non-crank windows after seeing virtually all motorized windows eventually give out in 90's models.
- oblio 3y agoThe 90s were 20+ years ago. We learned how to make reliable electric windows at least 15 years ago.
- kortilla 3y agoYour sample is biased to the very first generation electric windows which are definitely crap.
- wrycoder 3y agoWe had electric windows in the fifties and the motors were reliable. The usual problem back then was the window track lining (a fur-like channel) wore out, and then the window cocked and jammed when you moved it.
- pornel 3y agoICE power trains had so many inherent inefficiencies (in heat and friction), that aerodynamic improvements alone had minor influence on overall fuel efficiency, so it wasn't worth optimizing. But now that EV power trains are way more efficient, and batteries hold only a fraction of energy of a gas tank, drag became a major problem. Flush handles became a real aero improvement worth making. Digital mirrors are next.
- TX81Z 3y agoThe most aerodynamic car would have no doors, mirrors, or hell - wheels. Optimization is always about careful balance of objectives in light of a holistic experience. Anybody can “optimize for x” if you just ignore y and z.

- alexey-salmin 3y agoDoor handles don't have to be electric to be efficient
- pornel 3y agoThey don't have to be intuitive and easy-to-use either. It's a tradeoff. Automatically popping door handles have an obvious affordance and can be grabbed without needing some extra press first. I happen to have a car with non-electric flush handles ("chip shortage" edition), and I have to teach all of my passengers how to use them.
- mjhay 3y agoThis is a particularly, uh, interesting example with Teslas, given the number of people that have been burnt alive in battery fires, unable to escape (e.g. [0]). However, the Tesla electronic door things are much cooler than mechanical latches, so who is to say whether they are a good idea or a bad idea?

- AnimalMuppet 3y agoI'll say. If it's cool and it kills you, it's a bad idea.
- secabeen 3y ago> unable to escape That's a misleading summary. The driver was incapacitated, it was the first responders who couldn't open the door with the flush handles. The Model S in question has a normal, physical interior door handle. Presumably the first responder could have smashed the window and opened from the inside, but may not have had the tool. This outcome is indistinguishable from one where a first responder was presented with an ICE vehicle where the doors were locked.
