The infrastructures & cultures are significantly different in Europe. We're simply not going to turn into Europe by building separate paths... as if I could even *imagine* that being added to our transportation budgets. In Illinois, we don't even *get* what is added ot the budget - most of it never gets distributed and simply gets sent back to the Feds. Somehow they're supposed to send X percent of stuff back, so they take bunches of it from "unimportant" stuff like cycling facilities. (THis year, though, they didn't bother to distribute the funds for Safe Routes to Schools, so there are a few moms upset and of course it doesn't sound nearly as inoccuous as saying "well, we trimmed the budget from these cycling frills" as it is to have not given out the funds awarded to help kids get to school.)

Separate is nice, in theory... but again, unless that separate path doesn't cross other roads and driveways, every conflict is a gamble.

http://www.resourceroom.net/pcc/windsorpath1.htm is the photo essay I did of what's not such a bad path... but I can fully understand why somebody who wants to get *home* would prefer the road. Most of these issues would be just as true with the path on the other side of parked cars.
