My typical commute is about 9 miles and 15-17 minutes. Not bad. But Im often traveling, so then my commute is 2 hr+ (Im doing this at least once a week). With technology, its not so bad.
But no way would I have a routine commute that is the 2 hrs that many have in DC (on a daily basis) or the 50+ miles that some do, at least not here on the east coast. I did a 40 mile commute for a number of years, and it drags on you, especially when traffic and stoplights effect your times by a good amount. If I was in the country, or someplace not as dense, I might consider it, because a diesel, cruze eco, or similar car that gets good MPGs would make it a non issue cost wise... So then it is all about wasting life in a commute versus doing other things, and how that balances with amenities and where you live.
The country is diverse enough that there isnt a one size fits all answer, though I do see a ton of stupidity in long commutes in giant guzzling vehicles with one person inside. But they get their result at the gas pump.
