Learn to drive a moped, then learn to drive a car. If you didn't pass the moped test you go no further and can't drive a car.
I personally think it is a good idea
Cagers should learn what its like to drive a moped on the road before they step into a car, drivers will have a new respect for the biker
In the uk you have to have to take a shed load of tests to get on a moped nowadays, theory test, Compulsory basic training, hazard perception test and then if you want to drive a bigger bike, you have to take more tests again! (not sure what the deal is everywhere else)
p.s. I like bacon
