I've seen vehicles in parking lots that Don't have Handicap placards that aren't parked between the two lines.  Some of them are intentionally parked across two parking spots. Should those people not be driving as well?

I agree with the post above that said some stores have too many handicap parking spots.  I don't know if I have ever been to a Big Box store where all handicap parking spots are in use at the same time. Maybe in a metropolitan area that might occur. I have not seen in my area.
