I'm reading this and the voice in my head sounds like my Dad... So I apologize to anyone that thinks my comment sounds preachy...

First off, street racing is insane. There are lots of other cars around that have no concept of rapidly approaching vehicles and do dumb things when they see them (usually too late). You risk getting hit by them or hitting them. Dumb or not, they're not supposed to have to worry about racers on the street.

Let's say there's nobody on the street. OK, seems like that would make it OK... Well no, probably not. Let's assume (a$$-u-me) that nobody is in an altered state of consciousness. Let's assume (again) that the vehicles are in top-notch condition (tires, brakes, suspension etc) and are equipped to travel at high speed (what are your tires rated for?). Well the unexpected does happen, and stuff does break. Then there's this little thing called experience. Lot's of time behind the wheel of a vehicle traveling over 100mph? And here comes Grandma (Hey wait, she's not supposed to be here remember - the roads are clear...)

This reminds me of a thread a few years ago. On another forum (Jeeps) we were talking about (gasp) seat belts. The two schools of thought were to either wear them religiously or to stuff them into the crack of the seat and forget them. The context of the discussion was off-road driving in vehicles with cages, traveling somewhere around 5mph. This one fellow (decent guy, would give the shirt off his back, etc) firmly believed he didn't need seat belts. He really livened up the discussion and stirred up a lot of heat with the people who think seat belts make sense no matter what.

Well guess what? The guy goes off into the desert with good friend (two guys/two Jeeps). They both have a ton of experience in extreme wilderness situations, and off-road driving. The guy climbs a rock and does some driving around. On the way back he starts to drive back down the same rock and the Jeep falls off, he gets ejected, and his Jeep falls on top of him. His buddy couldn't get him out, help was forty miles away, and he died. No joke. We were all stunned. He was one of the better known people in the group. It really shook us up. You know the old saying? "It won't happen to me..." Well it can and it does.

Don't go out and get yourself whacked testing your car to see what you can beat. You can't beat physics. It's waiting for you to make a mistake and then it takes over. Go join Good Guys, SCCA, or some other group, get some driving school, rent some time on the track, and do it right. Leave street racing for the fart cans.
