That is probably the best post I have ever read on Slashdot. And possibly the best post anywhere regarding the 'which language / framework / stack' is best debate.

The only way you can know exactly how far you can push a car is to take it past the edge. The only time "conditions are safe" to do that are on a track, never on a road. You are kidding yourself. Yes, people don't need beer and ice cream but in moderation they're not going to significantly increase the chance you killing yourself or more importantly someone else. Roads are for getting from A to B not for having fun. If you want to have fun in a car take it to a track.

Getting back to the article... we are obviously a long way off being able to implement this sort of tech in the near future. But I think we could go some- way to improving things by having variable speed limits that are enforced properly. The car should receive instructions on how fast it should be going and should relay this to the driver so the driver can adjust things accordingly. The car could produce audible warnings so the driver doesn't have to take his eyes off the road and look at the speedometer. And if over some agreed distance the driver has gone above the required limit they should be fined.

You could probably write an App for it.
