It must be a rule of nature and traffic that the driver of the biggest SUV in the grocery store parking lot absolutely has to do one or all three of these things:
1) Stop their vehicle right outside the doors in the walk zone, even when there is plenty of parking out in the lot. And stay there, idling while their passenger goes in and leisurely shops.
2) If they do park in the lot, they must take up at least two parking spaces.
3) Once leaving the parking lot, they must try to turn left into rush hour traffic, away from a traffic light.
