Numerous Tesla owners have said they’ve been stuck inside their EVs after the cars suddenly lost power.

YouTuber Tom Exton claimed that his Tesla Model Y ordered him to pull over before it suddenly lost power and left him unable to exit.

Exton followed the instructions for the manual release to open the door, but he said this “somehow broke the driver’s window.”

    The ability to open a car door mechanically, from both inside and outside, should always be obvious, without having to find any instructions.

        Airplanes don’t have mechanical connections to their control surfaces anymore. They use triple or quadruple redundant fly by wire systems. But they’re that safe because of the FAA, not just out of the goodness of their heart. We need car regulation bodies to be closer to the FAA in stringency.

          IMO the biggest difference between standards in flying and driving is the training and requirements toward operators. Imagine having a DUI being a strong indicator that you’ll never drive again, or basic driver training taking 50 driven hours, in addition to stringent theoretical tests.

          Or people needing to check their cars for safe operation every time they start it, and omitting it being a crime.

          Or a significant percentage of the population being just medically disqualified from driving, especially over 60 years of age.

          It would be a different world for sure.

            I’ve always been strongly of the opinion that driving is a privilege, not a right and you have to prove you can properly handle the vehicle to strict standards. These vehicles kill and injure so many people every year because of awful driving and awareness.

            Now public transit on the other hand, should be a right.

      It’s no different than a steering wheel and brakes. It doesn’t matter if there’s some advanced electronics augmenting (or even controlling) those systems: there need to be a bomb-proof mechanical linkage as a backup.

        Tesla doesn’t use steer by wire, but some other car company do. It’s actually really nice for having a high steering ratio at low speeds and a low one at high speeds to be more precise.

        Plus breaks have been brake by wire for years now without mechanical connection.

          Brake by wire isn’t really very common afaik. Mercedes had EBC at some point but stopped using that system. It also had the downside that the SBC unit had to be replaced every so often to guarantee a working brake system.

            From the wiki:

            Ford, General Motors, and most other manufacturers use the same general design, with the exception of Honda, who designed a notably different design.

            Brake-by-wire is used in most common hybrid and electric vehicles produced since 1998 including all Toyota, Ford, and General Motors Electric and hybrid models.

            Seems pretty common to me.

              The three main types of brake-by-wire systems are: … electro-hydraulic brakes (EHB) which can be implemented alongside legacy hydraulic brakes and as of 2020 have found small-scale usage in the automotive industry; and electro-mechanical brakes (EMB) that use no hydraulic fluid, which as of 2020 have yet to be successfully introduced in production vehicles.

              The question now is what the other quote was talking about, seems a bit unclear to me. I omitted the electronic parking brake in the quote.

              EDIT: As of now I could find references to a total of 6 car models implementing brake-by-wire, two of which are already discontinued: Toyota Prius, Lexus RX 400h, Mercedes E and SL(both discontinued), Alfa Romeo Giulia and the Chevrolet C8 Corvette.

              Again, considering the current amount of models on the market, that’s far from common

                The Chevy Volt, for instance, has brake-by-wire, but I don’t think they advertise it as such. Most regenerative braking systems require brake by wire to function effectively, because you need to use the regen at higher speeds and physical brake at lower speeds, but only want the user to have one brake pedal.

          “Brake by wire” doesn’t mean there isn’t a mechanical linkage, just that the “primary” means of transmitting brake pressure is electrical.

          Between safety regulations, liability, the the potential for a PR disaster there isn’t a single road legal car for sale (yet) that doesn’t have a backup hydraulic or other mechanical system – the brakes must work if there’s a catastrophic electrical failure.

      I don’t see why critical controls like that – if you even want to make them automatic – can’t have manual and automatic modes coupled.

      If you lose power steering, you can still steer a vehicle, though you’re going to have to use a lot more muscle.

        Tesla’s retract the door handle for better aerodynamics. So you can’t open it mechanically from the outside without the handle to hold. I don’t know how the inside works. Plus they don’t have mechanical keys, so the lock is already electronically controlled.

          Maybe instead of engineering stupidly complex electronic door handles they could just, I don’t know, design a simple mechanical door handle that is also aerodynamic? These gimmick “features” automakers keep insisting on add pointless mechanical complexity, pointless areas of failure that are expensive to repair, and aren’t even something many consumers care about, or in many cases are overly complex hassles they actively don’t want.

            I’d be interested to see how much actual power savings you get from a more aerodynamic door handle anyway, but it seems that this could be handled by a simple locking flip down cover over a recessed handle if the savings is actually non-negligible.

              A flip down cover may be an option, but I’d worry about ice build up. How do you make sure you can always open the cover? If you add a mechanical assist, your back to your original problem.

              I think it’s likely the vibe and aesthetics though that caused Tesla to go with their super sleek ones over some sort of cover.

            You add drag any time there’s a divit in the panels. There’s lots of vortexes and disruption that happens just because of how your hand is shaped and where it needs to go.

            There might be a better way to do it, but the other car companies haven’t done anything yet that I’ve seen to drastically reduce the drag from the handles.

            Customers want range and saving money. If it does that without extra hassle, it makes sense. But that’s still up in the air. Especially with Tesla’s anti right to repair making things more difficult all around.

              It’s also completely possible to make entirely mechanical non-electronic flush car door handles. They’re less of a shiny gimmick than the electronic ones, and less convenient than many standard handle types, but are entirely possible to do. You could also hypothetically do a version that is both electronic and manually operable with the same components, entirely negating the stupidity of an electronic door opener with an entirely separate mechanical backup, provided you are willing to sacrifice frameless windows.

          I doubt that door handle contribites anything measurable to the aerodynamics of the car. The truth is that musk thinks it looks cool regardless of how annoying it is if anything goes wrong.

            I found a 12% figure. Aerodynamics are a primary driver of range, which is a major ev selling point. A 12% drag decrease is huge, because you can carry less battery which means you can have a smaller motor, lighter frame, leading to even more range. So it would be very important if that is true.

            The retractable door handle design allows radical aerodynamic designing for the side body panel. Retractable door handles are invisible handles that contribute by about 12% to reduce the drag coefficient of vehicles. Retractable door handles eliminate the issue of airflow bulge creation, air flow turbulence generation, and air flow pressure conservation. The decreased drag coefficient will also contribute to increasing the fuel efficiency of vehicles as there will be low drag generation resisting the movement of vehicles through the airflow.

              You can still have protrutionless handles without making them electronically retractable. Just have a spring-loaded metal flap that you push in with your hand

                You’ll still get the icing issues, where you need to be able to get in even with a thick layer of ice over the handle. But that does sound like a really good solution otherwise.

              I find it hard to believe that 4 door handles (being made flush with the door), reduces drag by 12% . Are there other articles you can share?

                That’s just what Google came up with, sorry. I don’t have time to research more right now. I do know a rear view mirror on an f350 has more drag than an entire Tesla, so aerodynamics are not always intuitive.

      i agree. and this isnt just a tesla thing. plenty of other manufacturers are going this route, tesla might be the worst though especially the 3/y rear seat release. when the i8 was released i watched a video on youtube where a salesman and a tech were showing the car off. the tech mentioned that in training they kept breaking the emergency release inside the car. if a tech cant get out in training then how the fuck is anyone supposed to use it in a real emergency?

      Absolutely. If your car is on fire, you shouldn’t be digging around looking for a latch, you should be pulling that handle and exiting in seconds. This design is going to kill people.
