Parking fees that rise and fall with demand can reduce cruising, but new flexible programs in San Francisco and Los Angeles suffer from a problem that is rampant throughout the state: disabled placard abuse. California allows drivers with disabled placards to park free for an unlimited time at any on-street meter. If cities increase the price of curb parking on crowded blocks to create a few open spaces, they also increase the financial incentive to misuse disabled placards. Higher meter rates may simply drive out paying parkers and make more spaces available for placard abusers.
