I have a little theory of why alot of asians cant drive and it has nothing to do with their eyes or any shit like that..
if you ever been to alot of asian countries they dont really drive cars, countries like Japan, Hong Kong etc rely heavily on cabs and train systems to get from point a to point b. I can tell you honestly When i lived in Japan I never drove a car once and pretty much every car i sat in was a cab.
My little theory to me also explains why most asian people arent as fat as us americansfor the most part because they are always on the go, when they arent taking the train to work they are usually walking and in a big fuckin rush to get from point a to point b. pretty much the day i left japan and got a car I must have packed on like 30 pounds in a matter of 2 years. They also dont eat as much shit food as us and eat smaller portions, im sure that fits into the formula
