Well, yeah, he's probably more of a worrier than the average person but it's the vulnerability of a woman alone that bothers him about the cycling. He obviously wouldn't worry about me driving places -- I'm in a car and less likely to get attacked, and more protected if I'm in a wreck.

While he's concerned about traffic and such, his real issue is a woman walking or running or cycling alone. It's not an unreasonable concern but he takes it a bit to extremes. And the Jennifer Ewing situation (and tshirt) just kind of brought the discussion to the fore again.

ETA: He won't buy a small car for the similar reasons. More likely to get crunched/killed by collision with an SUV, tricked out truck, etc. He just tends to err on the side of caution in general.
