Damn. Just tried that out for fun... and compared with MapQuest results.
From 6th/Broadway in LA to La Palma/Knott in Buena Park:
Public transportation: 120 mins, $4.35
Automobile: 31 mins (21 miles), $1.00 in gas + cost of car + cost of maintenance
Here in Montreal public transit is pretty good in the downtown and surrounding areas, but turns to crap the farther away from the center you get. I used to work at this warehouse in the west island and it'd take me nearly 2 hours (including a 15-min walk over a highway overpass.). Cost? I could buy unlimited monthly passes for $50 CDN, so the cost per trip (say 42/month?) was around $1.19 CDN. Regular passes were $2.00 CDN at the time.
According to Mapquest the same trip is around 25 minutes and just about 12 miles. If I had a used car for $3000 and used it for 2 years, that works around to $4 per trip (actually cheaper since I'm sure I'd use the car for other stuff, too). So say $3 per trip. Since it gets me there 3x faster, I say its worth the cost. If I had a more expensive car, I'd keep it longer so that doesn't make a diff.
If cities want congestion to end, they have to make more attractive public transport available. Those PRT systems sound cool in theory but are probably quite expensive to build (then again, so was the road system). Automated highways seem like they'll just increase traffic (in the long run, congestion returns) (as would the alternative of doubling highway lanes). Ah.. let's face it, we're screwed either way
