taking public transit? make sure your iPod's full of podcasts

I was dinking around with Google Transit tonight (mass transit planner) and made a few trip estimates. The total times are in minutes:

	public (walking)	car
friend's home (Plano)	65 (21)	23
Dallas City Hall	72 (7)	20
DFW airport	153 (5)	25
Love Field airport	122 (21)	21

The numbers in (parenthesis) are the walking components; the rest is via bus and/or (light rail) train. Naturally, this also assumes that all trains/buses are on time and (conversely?) there are no delays via car. Add the joys of public transportation: exposure to the elements (40C heat, rain), not to mention Air Guitarists. Still, the (subsidized) cost will be much less than buying /maintaining a car.
