Is there any way to find out the motivation behind this? And who is responsible for this part of the legislation?

[kelnos]

The latter bit was my question as well; I expected the article to share that, but no dice.

Motivation... I expect it's just another bullshit "law and order" law-enforcement power grab, thinly disguised as a "safety requirement".

General Motors, maybe?

If it is mandated that all cars should have this killswitch, then a lot of old-but-serviceable cars have to be taken off the road - and replaced with new ones.

[relaxing]

Of course the mandate won't apply to existing vehicles, just like every other new safety requirement didn't take all the old vehicles off the road.
