Can you explain the logic of this sentence? Unless probability is zero (a coin toss yields something other than heads or tails, and edges do not count), the odds are always in favor of 'sometimes', no matter what.

Anyway- I liken valet parking to skydiving, and self-parking to airplane travel. I can avoid the first behavior, which I see as far more risky than the second, mostly unavoidable, less risky behavior. Both involve going up in the air and coming down (analogous to parking the car so as to get to some place). I also have more control over my own parking situation than I have of air travel. I can choose to park far enough that Joe Sixpack probably isn't interested in parking there, squeeze next to a curb, etc).
