Yahoo seems to be working on some rather useful technology, especially for city-folk. Based on a patent filed by the company, the design calls for sensors attached to individual parking lots, sensors that will transmit data that can be tracked in real time on Yahoo Maps. It would certainly be very cool to be able to check parking space information directly from Yahoo Maps, though we wonder how effective it will be in the city, especially since the parking lot will probably be taken by the time you get your vehicle to the parking lot that you’ve spotted. But in any case, it’s cool, and we’re certainly hope that they go ahead with this.
