How about we make sure people can control a vehicle before we give them a license? Where I am, you can get a license without ever having driven on a highway, or over 50 kph for that matter. Ditto drive in rain or snow. Parallel parking seems to get the most attention during training. The test amounts to driving around the block in ideal conditions.
Couldn't even do that? Then come back next week and try again. Maybe it will be your lucky day and you'll have the "right" examiner.
