Louisville Kentucky has been working hard to improve things for cyclists.

They've added signage, sharrows, and bike lanes. The bike lanes are "door lanes", which sucks. Drivers seem to ignore the signage and sharrows. I've been yelled at to get out of the road, while in a lane marked with sharrows, and signs telling motorists to yield to bicycles.

The city has also been doing a TV and web campaign to educate drivers and cyclists about the law, and the city throws a twice a year bike ride led by the mayor. It hasn't changed driver's habits.

I'm not really sure much can be done at the city level to fix the mentality of most drivers.

However, I would love if the most dangerous intersections and interchanges with freeways had a bicycle bypass. I loathe riding where there are ramps entering and exiting to my right.
