I've been bike commuting so often now that I drive my car like once a week, and less than 15 miles total in stop & go traffic if I do drive. I'm totally loving the bike commute - getting better in navigating traffic, choosing the best roads to ride, and getting stronger.
Now I'm wondering if my dang car battery will die if I don't "charge" it by driving it! Who would have ever though! (Why are cars SO much maintenance....!!) Anyone out there ever ride so much that they tried starting their car and found the battery weak or out?
