Pretzel, I think it is not fair to compare it to gun control. Two different things. It's not political. Granted, it would take years to fully phase in... in accordance with the lifespan of cars. Have you known anyone killed or maimed by a drunk driver?
And I'd suggest you check online about how sophisticated these devices are these days... almost impossible to trick them with gloves or a buddy pushing a button.
When I'm driving down the highway and a mile away there's a drunk that's on a collision course with me, removing me from my son and my friends, I would hope he/she has the car that stops them from being on the road at that moment.
Just ordered a pair. I also thought they were black and white based on the early promotional pictures, but now that I've seen the video and the pictures @iacas posted, I like them much more.
I really liked my Slate Lime Originals and these look even better.
