OK, well..
To drive on USA streets the little car better be able to withstand a crash with a truck without looking like a beer can, and it has got to have high capacity air conditioning due to the hot and humid weather in the south (that machinery takes up space, so make room for it!). I use to drive a small car but after being hit by a caddilac, I will not do it again. But we do, and will always, have some pickup trucks in the USA. There is too much a hazard to drive small no matter how posh the small car is. I am 100% willing to accept less horsepower, but not reduce my own safety.
