Limiting the drive-thru?

The last people you would imagine finding at a fast-food restaurant are health-conscious bicyclists. Yet many bike riders are angry that chains like McDonald's and Burger King don't allow them to order food at drive-thru windows.

Most fast-food eateries, large and small, will only serve customers driving a car or motorcycle. They argue it's nothing personal, but allowing cars to co-mingle with pedestrians, motorized wheel chairs and bicycles, is dangerous for everyone.

.... "It makes no sense," says Wiley Norvell, the communications director for Transportation Alternatives, a New York-based bicycle, pedestrian and mass transit advocacy group. "If it's not dangerous in a bike lane with cars going 35 miles an hour, how can it be dangerous in a parking lot with people traveling less than 10 miles an hour? There are fewer safety issues than on an average street."

The article blurbed above talks about bicyclists being restricted from using drive-throughs by restaurants, but I'd like to see something slightly different take place. What I'd like is a ban on restaurants holding drive-through only hours (unless they also process pedestrians / bicyclists / whatever through the drive-through during those hours). If pedestrians can walk through a parking lot to get into a restaurant, why is walking through a lane so much more hazardous?
