Sillyness.
I've been trying to keep a log of all the times I use my car and how many miles I rack up. I've noticed that I could usually cut a few miles with better planning. Try to get things done all at once instead of going grocery shopping on Saturday, hardware shopping on Sunday, to the drug store on Sunday evening, etc. As far as the arguement that people like to be able to come and go from work when they please, well, I understand what they mean, but it doesn't work that way. Think about it for a minute. It's the same thing as saying that speed limits don't work because people want to get where they are going as quicly as possible, and they shouldn't have to slow down.
I think we need to have "city cars" if people are going to insist on driving alone. I'm thinking of something small and lightweight, with enough room for a few passengers and some carrying space. This is what you get to drive if you have a license. Then, you can also get a license for something a little different that can be used only on the highway. This would be a little heavier (more protection) and go a bit faster (top speed around 70mph). And you need a different license for these. Then, for moving things around in the city, you can have delivery vehicles. But you need yet another license for these. And to get it, you must not have had any accidents, ever, in a city or highway car. And if you cause an accident in one (heck, if you break a law in one), you lose the delivery truck license FOREVER. I know it's not perfect, and it would probably never fly, but I think it would solve a lot of problems. Could it really be any worse than what we have now?
