>What can be done to make biking more safer in the states?

Require more stringent testing to grant drivers licenses. It seems as though issuing DLs is treated too much as a revenue stream and not enough as an education/screening process.

I wouldn't mind using a rule where a certain number of DLs are permitted each year and that only the safest drivers get them. They are a responsibility not a right, yet we treat it like a right. Most likely self-driving cars will save us first, but if not some sort of leveling up system that awards points for things such as adherence to the speed limit or aggressiveness in acceleration/deceleration could be useful. All this information could be managed via a black box in your car. If you aren't in the top 80% or so, you shouldn't be allowed to drive.

Black boxes and mandatory cameras. Driving in the States is a "tragedy of the commons" issue without stricter enforcement.
