You should see the stink that some of the McMansionites here in Lake Forest Park are putting up about the MUP which runs through their private roads. Sure, they're happy that their dog walkers and nannies have someplace nice to take the pup and kids, but they're more than happy to pass illegal city ordinances to put stop signs on the MUP (and now they're fighting the repeal of their stopsign ordinance, and passing a new one to put in barricades at every intersection) because they might have to stop and wait 10 seconds for someone to cross the street.
The Lake Sammamish corridor of the regional trail network had a bear of a time getting land passage because the homeowners fought it tooth and nail. The main argument was that "bike trails bring crime to neighbourhoods", citing the incedents of majour metropolitan bike trails and crime statistics (when defending their stance against a bike trail through their very very suburban area nowhere near a metropolitan center.)
