"Cars are unsafe.

Not especially so, compared to a lot of other things."

Compared to other forms of intracity transportation they are horrifically unsafe. They are the leading cause of accidental death in America. They are safer than motorcycles but far, far, far more dangerous than other forms of transportation (which themselves are often dangerous only because of the risk of being hit by cars).

"Caring if other people use energy efficiently sounds way too much like ideology to me."

Highways are public infrastructure. Public infrastructure is by definition a public decision--you can't use public money to build freeways all over the place, fail to allow any other form of transportation, and then pretend it's a matter of individual choice whether people drive cars. And it's impossible to build car-friendly infrastructure without making unusable all other forms of transportation infrastructure as well.

Since public infrastructure is already a public choice, we have to consider all the consequences of that choice, which include safety and energy efficiency.

"Perhaps, but pedestrian-friendliness, bicycle-friendliness and mass transit friendliness are directly opposed to another kind of human-friendliness: the kind that allows people, especially families, to live at a comfortable density. The only way to make a city navigable by non-car means is to cram people in at high density: okay for some (heck, I live in a thirty-storey building myself) but not for others."

Research shows that human beings are not actually all that happy living in suburbs, especially if they have to commute two hours a day through traffic jams on freeways. People like towns just fine, but not suburbs. And a town doesn't have to be car friendly either.
