For one, our class went into this project with no idea what to do so it became more of a "who can use goolge better" contest.
Here's some tips for your car
1. Use a long boom & draw string
2. Put traction such as duct tape on wheels made out of items such as CD's
3. Fishing line is your best bet for the string
4. You get to go more than once so be ready to make last-minute adjustments after your first go
Hope it helps.
