Arguments for Recurring Driver's Tests

So lately as I've been wandering around Orlando, I've seen some rather disturbing driving habits that really make me wish we were required to pass a driver's test every 5 years or so. And not 75% or better pass, but 100% know all the answers kind of pass.
- Parallel parking against the flow of traffic. I still remember the one time I did this when I first got my permit. My mom practically yelled at me. It made an impression.
- And this one really scares me. At a traffic light at two 8 lane road intersections. On a red light. Making a U-turn. Could someone please tell me where this creative bit of driving has come from? I don't know where it's written that red means go.
- And then, of course, there's the drivers who refuse to share the road with bicyclists. As an avid cyclist, I strongly believe in the "Same Road, Same Rules" guidelines. This does require cooperation between motorist and cyclist. I admit to getting frustrated by bicyclists who don't follow the rules of the road, but I remind myself not to get too upset about it. Even the worst bicyclist does not deserve to have an angry motorist clip them with their car.
A friend of my sister's came up with an interesting idea, that I have expanded upon here. People should be required to first get lessons and a license to ride a bicycle on the road. Once that is accomplished (with a time frame of experience following), the next step would be a motorcycle. After each of these steps, you can finally learn to drive an automobile. The theory is that people would learn respect for everyone on the road--pedestrian, cyclist, biker or motorist. Because in the end, whoever is at fault for an accident between any of the above, the car wins.
