There is probably no need for Planners to consider this for Cleveland's downtown; however, this may be the way to help struggling neighborhoods within the city, as well as the the older, inner-ring suburbs - by encouraging pedestrian activity instead of vehicular.
I suppose the fast-food industry would put up a big fight to keep things as they have been.

Drive-Through? Not Downtown

The Lincolnwood, Ill. Plan Commission has wisely recommended against drive-through windows in its downtown business district, even via special permit. Such facilities have a negative impact on creating a pedestrian-friendly streetscape, officials concluded - and not only because they encourage people to stay in their vehicles.

“The facilities require additional curb cuts for driveways that cross sidewalks to provide access to the site,” Village Planner James Cox told the Lincolnwood Review. “This not only creates additional vehicle conflict points with pedestrians, but it also breaks holes in the continuous building facade of the downtown street, creating open gaps and a streetscape which is less appealing to pedestrians.”

Ah, lucky Lincolnwood, to have planners who understand the importance of aesthetics in creating a walker-friendly streetscape. There’s a lot more to it than simply assuring the presence of well-maintained sidewalks.
