[Number 3]

For more perspective, we have mandatory back up cameras in our cars because (and my memory may be bad on this) 6 or so children a year were killed by a car backing up.

Drunk driving? Half of all fatalities in automobiles (and motorcycles) are due to drunk driving. That's just the fatalities, not accidents or injuries. That's around 20,000 deaths give or take. So in the spirit of "hey we gotta do something about that", we get this.

So in the spirit of California, legislate it and they will come.

NHTSA will come up with a standard and it will go out to the industry for comment like they all do and then those replies will be reviewed and a new requirement may or may not come to be.

Have to agree, if you could keep drunks off the road we would all be better. So if you agree with that, how would you go about it? In Sweden, I believe one offense you lose your drivers license. When in business meetings if they plan to drink, they will get a room for the night.

But for the most part, this technology exists and is in use today. But it's generally optional and if you don't want to use ADAS features you don't have to turn it on.

We shall see how this plays out.
