I sure wouldn't put the blame for all these high powered cars on MEN. I've been honked at plenty of times by WOMEN in large SUV's with heavy feet.
And half of my bike club was taken out by a 5 foot tall woman driving a 4x4 pickup truck.

And when gas prices go up, if it hurts bad enough, habits will change.
It's the rare fool in Italy who drives a large car today.
But it's "unamerican" to suggest that we'd be better off with higher fuel prices.
