While I don't condone the illegal stuff on the video, it took a $450 negligent driving ticket for me to start calming down in my 20's. its perfectly fine to screw around in your car, just keep it to secluded areas where you arent going to endanger others. All it takes is one minor mistake and a lot of people can be on the losing end of that stick. I keep my bursts rational now, 0-110 on the freeway onramp as long as its clear ahead of me, giving me time to coast down to normal freeway speeds by the time I merge. Donuts in empty parking lots are a great way to have fun as well. Have fun but keep it safe and you will be around to have more fun more often.
