so when my car died, I inherited my wife's minivan. I only really drove it on weekends (mostly to go somewhere for long rides), and the battery kept dying on me. took it to the shop and they said "well, whoever owned this car before you had a remote starter installed, and it has been drawing current ever since." apparently she never noticed because she drives every day, but I figured it out in a couple weeks

hardcore is also when you experience severe discouragement when you are forced to drive to work, as I had to this summer when my kid needed a ride to camp not far from my office (13 miles, too far for him to ride w/me).
