I don't know if this still holds true, but in the past many of the Euro cars could not be sold here because they do not meet our safety standards or our emission requirements...
Fuels in the EU are generally cleaner (especially diesel). Cars which are more environmentally-friendly here because of the cleaner fuels are less environmentally-friendly in the US because the fuels are not as clean (look at the propensity of diesel-fuelled cars in the EU, which are often as clean as if not cleaner than petrol ones - they cannot be sold in the US simply because the quality of diesel there is several years behind).
As to the safety regulations - I cannot comment. I will say that some European cars are the safest in the world, and that Euro-NCAP, our safety procedures, are meant to be amongst the highest in the world. I don't know enough about US procedures to comment further.
I heard the reason that the US has a ride-height increase, though, was regarding safety in car-SUV collisions.
We do get TPM as standard here, as well as the lowered ride height. I would like not to have to put the front plate on the car, but there's not much I can do about that.
