>RHD vs LHD >metric vs imperial gauges (though those two both use imperial) >and an absolute ton of asinine schyte about lights including, but not limited to the following: -US cars can have red rear indicators, the rest of the world (who are reasonable) requires them to be orange. not entirely sure, but I think the US also doesn't like orange indicators in clear housings. -the US doesn't like sequential indicators, at least a big chunk has to be initially lit up, like the mustang -the US requires separate front, front-side, rear-side and side indicators, where everyone else is fine with front and rear (they often put reflectors in those spots) >going back to the 70s, US cars were required to have more obvious things like standardised sealed-beam headlights and chunky bumpers, and their speedometers weren't allowed to read higher than 85MPH. >and in general, emissions/noise standards are different all over the place, some countries are really relaxed, some are really strict, and some are strict but have easy loopholes that can be used, (like how in Europe currently automatic gearbox sports cars can have louder exhausts than manual counterparts.)
