Re: WTF??
If cars were newly invented today - you and I would never get to drive one.
You'd have to show that you'd completed not only your mandatory training plus X hours of on-road experience, but also sit exams in mechanical theory, legal liability and queuing theory. You'd have to show that you had a safe parking space, and that you knew what routes you planned to take everywhere. Then you'd have to maintain a log of your travel, prove that you'd driven at least 100 hours a year, and re-take the exams every 3 years.
Fortunately (?), cars were grandfathered in from a simpler time. But jetpacks would face all this and more.
