I almost always park at the far end of the lot, even in the "couldn't care less" Subaru. Why?
1. It's almost always difficult to get in and out of close spots. Pedestrian traffic, more cars, etc, make it difficult.
2. I'm more than able bodied and plan to stay that way. A little extra walking is good for me.
The exception is when there's been a lot of new snow and I'm pushing a full shopping cart. It's damned near impossible to get a cart into the "hinter regions" of a parking lot in those conditions. Otherwise, I'm at the back...
