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.
It's no more effective than ridiculous gun control proposals, and for the exact same reason - there are so many cars out there not subject to the law already that it would be pointless.
It's also rendered completely ineffective if the driver wears gloves or their buddy pushes the button. It's a useless piece of tech that will do nothing but make senators feel good about "doing something" so they can pat themselves on the back while in reality nothing changes except making life worse for law-abiding citizens.
Those who would give up essential liberty, to purchase a little temporary safety, deserve neither liberty nor safety.
There would be a lot of details to hammer out but I'd support it. To me a minor inconvenience is worth the price to pay to know that others aren't out there driving while drunk. At least the ones driving newer vehicles 😉
