principles:
maximise potential energy
minimise adverse forces (weight/friction/etc)
maybe a rubberband
just wind it up,
remember those cars you had when you were a kid, that you rolled backwards and let rip.
get a good quality rubber band/elastic
my choice:
just make a cool looking car, add like 10 wheels, give it a paintjob.
give it some speed strips,
