Place duct tape stick side up across the road. When cars run over it, it sticks to the tires and sounds like they have a flat tire, then they get out and have to take it off.

You might only want to do one lane at a time, it saves duct tape and is better.
After we went Penny-tapping, we went Duct-tapping and made like four cars stop in a row.
