Drive Score shows a map of what establishments are in a property’s neighborhood and calculates a Drive Score based on the number of places within a convenient driving distance. With Drive Score, buyers can see how close establishments are by car. Homes are often located in an area where restaurants, libraries, grocery stores, hospitals and other businesses are easier to get to by car than on foot.
Drivescore assumes that parking is readily available at all locations. I'm not sure how this is different than "places nearby," but it is what it is. A convenient driving distance can be pretty far. My neighborhood still scores higher on Walkscore (98) than Drivescore (87), fortunately. If parking was taken into account my scores wouldn't be close at all.
