The Google Maps made one of its most useful updates showing whether a location, such as a building or a restaurant, is wheelchair accessible.
The sources of information for these updates are essentially its users Google Maps, who record and answer questions about the places they visit, indicating, for example, the average cost of a meal or parking space, etc.
The service is not yet available for Greece, but if you travel to America you will find wheelchair accessibility under the Amenities section when searching for a map point of interest, and you can also add your own conclusions.
The new feature was built by Rio Akasaka, one of the Google Drive executives who took advantage of Google's right to its employees to work for 20% of their time work on their own designs.
