They won't behave like trains. Trains have tracks and are tied together. Their condition is also doesn't range from perfection to Judy's beater.
Judy's car won't. And I'll bet that they never take away the brake pedal away from the driver. And that's how a blow out turns into a spin.
You're asking a lot of this computer. A lot from the lowest beater on the road. And if you think a blow out is the worst thing that can happen to a beater, you haven't spent enough time on the south side of chicago to see what utter crap people will drive.
Are you sure that computer will be able to tell a blow out from a busted ball joint? how will it handle a locked rear axle because the diff fluid leaked out? There are so many possible spectactular failures. The first one at 90mph will insure that the computer speed is dropped to 50mph or less. Even if it's initially for a few months to improve the system.... remember that temporary speed limit we got when Nixon was office that lasted for over 20 years and in some parts of the nation it's still in effect?
