People who wants to test the limit of their car should go to the "track" regarding how much you paid for your car. It just plain stupid doing such thing in public roads. If you can't afford couple bucks to go track.... you should be ashamed for owning a 50k-60k car. Below are the reasons why you shouldn't speed even in public road.
1) Even if you are alone on the road, you may cause an accident by yourself. To clean up that mess, tax payers have to pay for it.
2) You may die and be on the news and be remembered as the "dumb fucking ricer"
3) Obey the law
