The bastards just don't look, because they just don't care.
Best option is for legislation to impose 2 years of full motorcycle license before you can apply for a car learners permit.
Take for example, places in Europe where teenagers are allowed to ride scooters everywhere.
Once they progress to driving cars, guess what? They are motorcycle aware!
That kid on a scooter could be a younger sibling, cousin, niece, nephew etc.
But the cotton wool wrapping fun Police will put the kybosh on that.
