Using church parking lots as park and rides.

As I drive through Minneapolis, I often hit traffic.  It's not just annoying; it's stressful and wasteful.  Stressful when we wait for extended periods of time, just trying to get home or to work. Wasteful in the amount of time, energy, and fuel that is spent in traffic.  While buses, trains, and carpooling are obvious solutions, these methods are either being put to use already or are not convenient enough. 

However, is there a better short term solution?  I think the answer is yes, but we also have to address the problem.  Honestly, the main reason seems to be convenience, though many other reasons likely exist.  So, there is a fairly simple solution that can benefit both parties, and it's using church parking lots as park and rides.  People who work around the same area can meet at a church that's approximately however far (one mile or ten miles or however many miles).  A church charge people to park there for a minimal price (which is helpful to them), and people can meet there and head to work.  This doesn't hinder convenience significantly, and it lessens congestion, decreases stress, and saves fuel.  It may seem like it wouldn't make much of a difference, but we need these sorts of solutions until better options emerge.  It's just an idea, and it's probably flawed.  What do you think?
