Collectively decide and easily are carrying lots of weight here.

Americans (citizens that is) have held fairly consistent opinions on healthcare, guns, education, war and yet very little changes because all voices are in fact, not equal. We are not collectively deciding. There are massive thumbs on the scale, often in favor of private profit that keep things as they are now.

Some might even, surprise surprise, be owned by the companies investing in the companies that use this technology.

This is, as the OP noted, a gross invasion of privacy and not avoidable in a country that largely requires cars and their registration for day to day life.
