Diesels are accepted more outside the US. There was a bad rap regarding diesel in the old days because (1) the mechanical-timed injection got out of adjustment so the vehicle was smoky and stank and (2) you had to go to dirty truck stops to buy diesel. The yuppies didnt like either so nobody wanted diesels. Now, the fuel is cleaner, injection is electronic, there are soot traps and the fuel is sold at more acceptable locations. Of course, now the yupsters want a solar car that runs on their own farts when it is cloudy out.....we dont want to buy foreign oil but we dont want to use our oil.....instead we want to raise taxes and subdize marginal technology....go figure.
