I don't think I've ever gotten a why. Maybe if I rode further, but mostly the first quesiton is "how far do you ride," and the whole thing become self-explanatory with "about 16 blocks." Still, I do always get a laugh when people go on gas price rants. The difference between $0.75 and $1.50 gas is about $20/month to me, and it doesn't generally swing that far.
