Thanks guys but I know how to do the conversion, I'm not an idiot. I was expecting utter craziness of a guy doing 240 mpg in a 70 mph. 240 km in a 70 km is still crazy fast for the streets though.
Also My wording made it not clear but what I meant by "It's a pain to use metric when everyone uses standard," What I meant was that I like to use metric, but everyone IN THE STATES uses standard so it's a pain for ME to use metric in the US. I'm not confused here, just bad wording.
