Customers require protection at specific traffic points. These points are where vehicles change directions, where pedestrians walk across the vehicle path, and where vehicles park. We also know many adverse things about the drivers who enter parking lots. A statistically significant portion are drunk, high on drugs, or visually impaired. This is especially true during evening hours.
Some drivers suffer from emotional or mental disorders, and some are immature and inexperienced.
Extent of the problem It is difficult to determine the size of the problem. Anecdotal evidence suggests that convenience store accidents are epidemic. We examined police records in one city with a population of 500,000 people. The search produced two cases where the vehicle jumped the sidewalk and struck convenience store patrons during one year. In other incident the same year, a car hit a customer standing six feet inside the store.
