I meant biking accidents this product is obviously trying to solve.

> And cars have no business being on other roads as long as highways exist ;)

Biking lanes are not comparable to highways. Where I'm living, if you bike on car lanes when biking lanes exist, or if you bike on sidewalks at all, you get a hefty fine depending on the situation and if you possess one, you get points on your driving license.

Exceptions are turning, leaving the road, the lane being blocked by a clueless driver etc. obviously.

Cars are also not allowed on biking lanes, neither are pedestrians. Same exceptions apply.

Highways are more comparable to railroads, maybe.
