And the motorists have trouble realizing that anything has changed.

I don't think it's the motorists having the trouble, Sparky.

It's the motorists who are preempting other people's long-established right of way, and polluting other people's neighborhoods with noisy, dirty, and dangerous traffic.

The same motorists who do this will fight to the death to keep anyone from impinging on their own little cul-de-sac. This is why the cul-de-sacs tend to empty onto the same jammed arterial roads; no one wants cross traffic cutting through the back way.

Suburbanites tend to have a bad case of "I've got mine; I'm pulling up the drawbridge behind me; but I'm ready to steamroller your street to add another lane."
