By looking at how other countries do it. In Germany you actually have to drive on the motorway at high speeds as part of your training . I have a friend who was told to drive at 120mph during his training, and the instructors argument was "the road is empty, the weather conditions are appropriate, and there is no speed limit on this stretch of the road,so you should know how to handle the car at those speeds". Yet in my own country I know people who have never driver faster than 40mph during their training, yet the legal motorway speed is 90mph. Are they ready for driving at those speeds? No, they are not.

And the argument "what about woman driving while talking on the phone, eating and tending to children??" is completely pointless, just like "what about drunk people driving??" - both of these groups of people should be banned from driving, as both pose a danger to safety on the road.
