>All modern cars have been locking the doors for the last 20 years or so, as far as I know. Yeah, and I would always disable that feature. Perhaps that was wrong to do, and now that I don't have a choice it's actually safer for me and my passengers.

I hate this "feature". Was there a rash of children jumping out of cars that lead to its creation? It just seems like such a narrow set of facts where a child is big and smart enough to open the door but dumb enough to jump out and get seriously hurt. Opening a moving car door is presumably quite difficult given the aerodynamic pressure on the body. So the car would have to be moving rather slow and yet turning and moving fast enough that the child couldn't avoid disaster.

    I was talking about child locks which can be opened from the outside and increase the risk to children in the event of a car jacking.

  If you're talking about the child safety, it's unrelated to door locking. It prevents children from exiting the car before an adult can ensure it is safe to do so. Mostly to prevent the child getting run over by a passing car, or dooring a passing bicycle. If you don't like it you can just not enable it.

    Yes, and actually this makes a ton of sense. I perceive the risk of my children opening and falling out of the moving car as low relative to being trapped in a car in a bad situation. But I could absolutely see the idiots trying to bolt 0.28273 seconds after I put the car in park. I'll update my thinking.

  You may be on to something. I drove a BMW that, when the electric window position sensors went bad, the whole car went into limp mode and didn't let you accelerate over a certain speed. I imagine the rationale being out could not verify the windows were not down? Crazy still... the first and only BMW. I should have stuck to old Nissans

    Things go wrong on cars, it doesn't mean they're bad as a brand. I loved my BMW. Have a Volvo now and apart from the slightly crap entertainment software I love it. They're replaced the software with carplay in the newer models, and updated older models, but alas they can't update my model due to a hardware mismatch. It's the cars where things constantly go wrong that you should avoid. Jags + Land Rovers have those reputations in the UK.

      It's fine that a window position sensor might eventually fail on a car. It's not fine that a window position sensor causes the car to limit its maximum speed.

      It was less that it went wrong, and more that when something small went wrong it became a complex issue due to how the system was built, and how it handled a module failure. The car was entirely capable of continuing to operate normally, but the operator is not trusted by BMW. Their ecosystem locks out the owner from easily maintaining their car as well, which made even more painful as I had no trouble identifying and sourcing a new module.

    That seems an equally insane reason to make every car everywhere auto-lock on drive, given the safety considerations of default unlocked. By all means let's increase common risk severity for everyone in order to demonstrate we're doing something about a rare tail risk. /s

  > Opening a moving car door is presumably quite difficult given the aerodynamic pressure on the body. So the car would have to be moving rather slow Actually, no - at least not slow by my definition. You’d have to drive over 130km/h, this is when you need some serious force to open the door more than maybe 10-20cm - but anything slower than that, it’s still pretty easy, certainly easy enough for a kid to open the door wide enough to fall out or get in serious trouble..

I had to guess, I'd guess you aren't a parent or spend much time interacting with children :) Also, auto-lock reduces theft and carjacking risk, which is nice.

    Parent of 2 actually, and lots of time. I'm talking about child locks, not auto-lock. Locking the door from the inside. A commenter above suggests that it's to stop the little idiots from popping out into the middle of the street .7845 seconds after I put it in park. That actually makes some sense.
    - EForEndeavour 1y ago
      Ah got it. The conversation upthread had focused on auto-lock, and someone had mentioned child locks in passing, and my read of your comment was on the auto-lock on shift to drive (or on starting to move). And my bad for falsely guessing you weren't speaking from personal experience!

  A friend's 3 year old absolutely opened the door last year while we were driving. Luckily she was strapped in her car seat, but otherwise could've easily fallen out.
