When I'm done shopping, I find one of the shopping cart corrals much farther away, because it is mostly free of nearby cars. Once I get almost there, I play shopping cart horseshoes and launch the fucking thing with all the pent-up energy I saved from not being allowed strangle any annoying co-patrons.
It's like horseshoes, because close counts as a score. Sorry about the occasional "Beamer" parked unfortunately in range, so as to not get pranged by other doors.
