In situations like this, a lot of what counts is someone's attitude. There's a big difference between a situation where you calling a friend in an emergency, or having a standing arrangement where you carpool somewhere, when the person getting the rides is grateful, offers to help pay for gas, and takes other options when they are possible, and provides other useful things to the friendship, and someone who demands chauffeuring on the spur of the moment for convenience rather than necessity, is snotty when the driver is unable to come, and is only in the friendship for free rides. One is being good to your friends, the other is mooching.
