A trivial epiphany from this afternoon: the theoretical case for jaywalking is identical to the theoretical case for allowing right turns on red, namely, that it’s utterly silly to make people wait around for no reason. At least in New York City this translates into the same legal status (namely, neither is allowed), though presumably enforcement is not symmetrical. But everywhere else there seems no good reason to allow one and not the other.
I’ve also been struck by the fact that in Minneapolis, pretty much every street corner is substantially curved. This gives the strong impression that space belongs to cars (particularly, turning traffic), as the very structure of the street gives them priority. It also notably lengthens the distances pedestrians have to go from curb to curb.
