Thanks for the tips, but I don't know if these will work in the U.S, the highway here can be curvy, but the minimum distance between cars are usually more then 50 meters. It's also a fact that the cars travel a lot faster here on the highway, 65mph is the normal speed limit, and the cops don't pull you over unless it's a holiday. 作者: xiaodao2008 时间: 2009-10-12 12:33
