Here's a crazy idea:
The public SERVANTS should have to take the bus and walk instead of park. Citizens should be able to show up on a whim and find parking.
Making the servants walk would do several things:
Only true servants would bother, not people seeking to be ensconced in a lifetime job in a public sector union.
It would remind them every day   that theirs should be a servant relationship and not one of "high makamaka" insulated from us .
