Automotive supplier Bosch wants to help guide drivers to vacant parking spots in more than a dozen U.S. cities this year. The German company says it's been testing its "community-based parking" initiative in Stuttgart and other German cities and will launch it later this year in as many as 20 U.S. cities, including Los Angeles, Miami and Boston. The company says it will be working with automakers on the initiative but didn't say which ones. As cars drive by, they will automatically recognize and measure gaps between parked cars and transmit that data to a digital map. The company has been pushing a number of smart-city projects, including internet-connected sensors to monitor pollution, allergens and flooding.
