Every where I've ever been drivers tend (there are always exceptions) to drive in outside lanes a fixed distance from the lane stripe to their left, regardless of how far the curb/edge is to the right, especialy when they are "at speed". In other words, the left tire track tends to be about the same distance from the left stripe of the outside lane, regardless of the width of the the outside lane. I've never measured it, but I suspect it's always around 2-3 feet from the lane stripe to the left.
