@R. David Case, why do people judge you so harshly? For one, you say you "give" your CDs to people, yet you charge $15 for them. So you lied about that, which typically suggests that you might lie about anything for a few dollars.
The photo of your solar-powered truck looks ridiculous. The wind generated by going over 10 miles per hour would destroy those large pizza box-like panels you placed on the hood and the cab—unless, of course, they were indestructible and glued on with something like Gorilla Glue. In that case, a strong gust of wind could either blow you off the road or flip the vehicle over. But just for fun, I will search online for solar-powered trucks and see what I find.
By the way, how do you pass buses or semi-trucks without making contact? You can't. You just can't.
