Who does what on purpose? It's the US that for some reason decided to differ from imperial units. The UK gallon is just the imperial gallon. There's also imperial fluid ounces, imperial pints, imperial quarts, and imperial tons. There's also imperial units that for some reason the US does not seem to use altogether. Like stone, for instance. Why not? I don't know. [/offtopicstuff]
So you have a paramedics and firefighters a minute away to help you when you slide into a pole or crash into someone's house? Also, I went to a drifting/racing event at a track near me, and the only bad accident I saw happen was a SpecE30 car flipping over. But it was very low speed, just due to a poorly placed embankment. But do you know what he had? A helmet, roll cage, and 5pt racing harness. Who uses that safety equipment on the street?
Also, the drifting that I saw, the drivers also had helmets, roll cages, 5pt harness, etc. And none of the drifters crashed into any static objects that I can remember, despite a few of them going onto the dirt a few times. They also hit one another a few times. Then again, those drivers were actual drifters (XDC), not kids doing burnouts on public roads.
Who cares too much about how off their speedometer is? My car has 185/65r15 stock, but my summer tires are 205/50r15. It helps keep me from getting speeding tickets lol
