This is the originally unintended side effect of regulation that applies to cars.

Americans generally don’t want tiny vehicles. The option that leaves them is trucks and, increasingly, SUVs.

I want a tiny car. The problem is that road design is unsafe so people buy bigger cars so they are safer when they get into an accident. I've seen the aftermath of a Chrysler Fiat getting into a collision with an SUV and lets just say the Fiat driver had much worse day than the SUV driver.
