Why can't there be a go fast sticker affixed to the bumper of someone with a high performance car who has gone through racing school and has demonstrated the competency to drive safely at speeds of (for example) 100 mph along rural interstates like I-15 from Southern California to Las Vegas?
Better yet -- why isn't that level of driver training available to everyone?
Oh yeah, because it costs money, and us Yanks will raise hell if the poorest of the poor can't afford such classes if the licensing process requires them.
The result, of course, is that we have millions of inept drivers who were "taught" by poorly-constructed half-assed classes in school parking lots and in Uncle Jeb's farm truck.
