A car in the air

I was walking to school and saw a car hit a bump and go into the air a little. Then I was wondering if it was possible to make cars light enough to be able to use other cars as jumps. Like a Lamborghini being a flat slant at the front of the car. Then a truck light enough to go off it as a jump. This would be fun but dangerous. But recklessly, it would be just fun. I would be reckless most of the time, get on a freeway, and speed as fast as I could. Then I would hit the front of the Lamborghini and glide through the air. Then these cars are light enough that they don't just fall straight down, but they hover slowly down. This would be so much fun.
