it's very difficult to have a viable intercity public transportation system outside of the bowash corridor because of the distances involved. but within cities i would like to see more focus on building and expanding safe (meaning less crime!), extensive public transport instead of building more freeways.
i didn't buy my first car until i was 28, and that was only out of necessity. living in new york city and in the UK one doesn't really need a car (well, if one lives in west wales it might be a different story...), and i don't feel particularly attached to mine. but without it it would take me lord knows how many hours to get from point A to point B, not to mention the buses don't reach all points in orange county.
for an interesting take on americans and our dependence on cars read this short essay. we read it in 7th grade without knowing about whom we were reading. we all agreed that these were uncivilized savages...until we found out what the article was referring to. then it came as quite a shock!
