I don't think in general food delivery drivers get compensated for gas so that would be just about the only time I personally would feel obliged to tip - and I mean in places where things are fair, not the U.S. Otherwise I think tipping is a thing people should probably stop doing, or at least to the extent they feel obliged. I've gladly tipped people sometimes when I feel like they went out of their way, but the stigma has to stop.
