I have been in the US for 30 years but metric is way better... all that nanometer stuff in your computer is metric not imperial as well
for example a 10cm cube filled with water weighs 1 kilo and is 1 liter, boils at 100 degrees. In the US you deal with cups pints, quarts, gallons... and you can't even convert easily between dry and liquid stuff
I do agree that steering wheels should be on the left :-)
