I'm just going to get on the advocacy high horse here:
It's always a driver - a person - who crashes into a person on a bicycle. Unless the car/truck/van is an autonomous object with no human inside, it's always a person striking another person.
And it's always a crash, not an accident. An accident suggests that the interaction was unavoidable. In this case it certainly was avoidable.
OK, dismounting the horse again...
. . .
First off: driving is not a right, but a privilege. So the best thing is to revoke this kid's license to drive until he's 18. In my ideal world he'd have it revoked in perpetuity, but wishes and dreams and all that...
And the bike idea is fantastic. Add to that a transit pass and it would be ideal. A creative judge would issue such a sentence. And sure, his parents or siblings would cart him around but there are ways of enforcing use of the transit pass, at the very least (its use can often be traced if the pass uses RFID technology).
"Smoke rolling" or "coal rolling" is actually an enforceable offense in many states, including Virginia and Maryland.
My guess is that this teenager inherited this reckless behavior from a parent. It's not uncommon for young drivers to model their biases after those of their parents.
