But the consequences are so great that people will think twice.
I think I would technically keep driver's licenses, but you'd just have to fill out a form to get one. If you're caught driving drunk, then it should be revoked in court.
Personally, I have no problem with how it's done in BC. Here, we have to write an exam, which, in the event that we pass, gives us access to a class 7L "learner's license", which entitles us to drive as long as we have someone with a class 5 (full driver) in the car with us. After a year, you can take the class 7 road test, which gives us the class 7 "novice license", which entitles us to drive alone as long as our body alcohol count is exacly zero. After two years of that, you can take the class 5 road test, which finally gives us the full class 5 license.
The main objective behind this is to make absolutely sure that those who are allowed to drive are very competent at doing so.
I'm not sure how it's done elsewhere.
I will admit that some people seem to get worse as they get older and are not required to take any additional road tests even so, but I feel that the license method is a step in the right direction above just letting anybody who can afford a car to drive one.
