Completely agree that standards are very strict. That's why they're rare. But code are written by humans, and mistakes happen.

Remember the hundreds of Toyota acceleration cases? They attributed it all to faulty pedals or floor mats. But multiple lines of evidence has come out that the ECU code had a critical flaw and at least some were attributed to that malfunctioning.

ECU-related SUAs are more common than you think.

I don’t know, if we can teach people to turn into a skid, can we not teach them to pick up their foot in a sudden acceleration?

I mean, the signs are pretty easy to spot. And the thing is, I’m not sure this falls under aggressive driving. Would be happy to hear of a case that says otherwise, but it seems like these are generally treated as accidents.

I’m not saying throw the person in jail. But driving safely requires good reflexes, and an accidental acceleration suggests the driver’s reaction time is deteriorating. Maybe we have them take a test and they do fine, it was just a one time thing. Fair enough, give them the license back. But it would be nice if the system actually tried to proactively weed out bad drivers instead of waiting for the worst.

The scary thing is that it’s something that can happen to anyone. It doesn’t really mean you’re a bad driver. It’s a slip of the foot and when the car doesn’t do what you expected a switch flips in your brain, you panic, reason goes out the window, and you double down on what your panicked mind thinks will help. There’s no chance you will pick up your foot in that moment.

You’re right, a panic response like this has killed people, but vilifying the driver doesn’t help. It’s also hard to see how a law would. This kind of thing is probably already covered by reckless driving or something similar, and if you actually wanted to create a law that targeted hitting the wrong pedal how would you prove it?

That's an exaggeration. There is no car out there that has "hundreds of computers" in it, unless you take an extremely loose definition of "computer" that is something like "a chip with transistors in it". I think any reasonable definition of a computer involves being reprogrammable (even if only with in-depth servicing), and I don't think you'll find hundreds of devices in a car that meet that definition.

Everyone's saying it's panic hit-the-gas, which likely, but there are documented cases of cars uncontrollably accelerating without the accelerator pedal being depressed at all.

It happens when the voltage to the ECU fluctuates so much that it bugs out and gets stuck sending a 100% accel signal to the engine. Cars these days are governed by hundreds of chips and have numerous electronic components, so makes sense that they glitch from time to time.

If we had sane driving laws that prioritized pedestrian safety, accidentally hitting the gas when you meant to hit the brake would result in a automatic license suspension and a mandatory remedial driving course until you can prove that you do, in fact, know how to do the most basic thing we expect drivers to do.

But instead it’s just another oopsie that, fortunately, didn’t kill anyone this time.

I've seen so many people starting to run reds and do three-points on busy roads since the start of the pandemic. If there was ONE thing I'd want more cops to do it would be getting these people tickets, points on their license, temporary suspensions, etc, until the behavior became socially unacceptable again. It's starting to feel legitimately unsafe to exist as a pedestrian.

Once saw a Denny's with an old lady's Buick driven right through the wall, in the middle of a(n empty at the time, thankfully) booth. The place had parking spots perpendicular to the exterior wall - panic hit the gas instead of the brake, jumped the curb and drove it right over the sidewalk and into the restaurant
