Seems incredibly dangerous. Imagine some bad GPS reading warps you from a highway to a school dropoff zone and decelerates you to 20mph

Minus the word "incredibly" which is quite an exaggeration, I agree. But, it can be made pretty safe. Entirely safe in fact, for good drivers (less so for shoddy ones)

The fine details of implementation are not noted so we can only speculate. I would hope it's designed to very gradually start limiting the speed after X seconds of alerting the driver. That said, even the most naive design, which would work the same as RPM limiters (which all cars have to avoid engine damage) would just cut fuel injection whenever over the limit. This produces about the same effect as coasting in neutral, so even then you are going to coast to a stop very very gradually and have lots of time to make it to a shoulder.

That said, even that does present some danger -- not to me or you of course, but you know, to shitty drivers who might not be accustomed to driving cars that fail at random and might panic and fail to cope appropriately with the situation. I mean, I have even ridden with drivers who are afraid to stop on the shoulder, even in a situation that warranted it, so it's bound to happen now and then. A manual override if available, will help here, but the pool of drivers dumb enough to still be startled into making a mistake will merely shrink then, not disappear.

I actually wouldn't mind a thing like this that I can manually enable, I am constantly afraid of accidentally speeding and always have my satnav on so it shows the max speed (here in the UK we get penalty points, not just fines, and enough of them can mean you have a temp ban from driving). Don't really like the idea of this being automatically triggered and enforced though.

This is great, data shows that beeping is effective for increasing seatbelts usage, I see no reason why this wouldn't apply to speeding.

I hope they take this a step further. Cars should not be able to exceed 90mph unless you have a special license for the track. 99.9% of drivers are not tracking their car and theres absolutely no reason a 6000lb pick up truck needs to go 150mph under any circumstance.

Actually I find this stuff pretty annoying already. Cars nowadays (some do it worse than others) "alert" you of lots of stuff. Such as "lane departure" beeps if you didn't use the blinker. Yes sure, using the blinker is a good idea. Is it really 100% necessary in all situations? Absolutely not. Of course technically the beeping car is correct and making you adhere to the rules of the road. In practice it's just annoying.

Now queue this. This has the potential to really go incredibly wrong. You mention shoddy drivers for who it can be pretty unsafe. Even if there's only a tiny percentage of drivers out there that is shoddy, multiplied by the number of drivers, it's still a lot. And I would argue that the percentage of shoddy drivers is actually not such a tiny percentage but a larger one.

This has to be automatically overridable. I.e. by simply hitting the gas pedal. It can't be something special you need to do. If there's a dangerous situation on the road that can only be avoided by speeding up beyond the speed limit, I don't have time to remember where that extra special button is that I almost never use. I need to be able to just hit the gas pedal. If you're wondering what situation that might be, there's actually such a situation that I remember from my driver's license test. Basically something unforeseen happens (don't remember the specific, but let's say a car shoots out of a hidden driveways or something) and you have no space on the left or right (let's say a bunch of trees, houses etc.) so you can't just go there. You don't have enough space to stop the car before hitting that car, so hitting the brakes is out of the question. You have oncoming traffic on the other lane as well but that car is still far enough away that if you shift down one gear and hit the gas pedal, you can swerve around the unforeseen obstacle without crashing head-on with the oncoming traffic on the other lane. I need one hand to shift, the other to steer and those two things already take all of my concentration not to mention the split second decision to see that braking will cause a crash while speeding up will save the day.

Nice "trick question" though :)

Unlike the seatbelt chime which is easy to address, speeding beeps would be maddening. Everybody speeds at some point while driving somewhere. Not all speeding is reckless.

As far as making someone get a special track license, that just seems like overkill.

I find it hard to believe that the car would base that solely on GPS readings, it will likely be a combination of multiple systems, including cameras which read signage as you pass it, which is already commonplace in many newer models.

The beeping is effective for me disabling the sensor/buzzer altogether in my cars. Fucking hell, I know when I'm not wearing it, or when I'm speeding. Let me be the judge of when I do whichever of them.
