Probably, yes. But right now I'm gunning for the low hanging fruit. The argument that cars are overused does not hinge on whether carpooling is a fruitful endeavour or not.

After all, it is not impossible to imagine that the reason carpooling works at the moment is that our present automobile fleet provides ridiculously excessive capacity. If the only people who had cars were the ones who actually needed them, there might not be enough slack in terms of cargo capacity and passenger space to enable carpooling, unless you deliberately designed your city planning and business practises around it. Which may or may not be worth the bother.

Now, I do think that carpooling will be worthwhile, even in a low-car infrastructure. But unlike cornucopians, like Julian "copper can be made from other metals" Simon, I like to accompany my policy recommendations with some back-of-the-envelope arithmetic showing that I'm at least in the right ballpark. And I just don't have the information to do that on carpooling.
