If you did this to me I would SLAM on my brakes. Rear-ending a car is 100% the fault of the person behind, no ifs ands or buts. Open and shut case. I get my car repaired for free (there was a small scratch on my bumper anyway), you probably total your car, your insurance skyrockets, your parents take away your car...was it really worth it? You are the reason insurance is so expensive for young males.
even considering you get your entire setup for 400 dollars, then 300-400 dollar student rate season passes... that's a hell of a lot more than a basketball or a soccer ball costs... and the costs for that could be split between multiple people who could use the gear simultaneously
