Each week, we spotlight a cool innovation recommended by some of the industry's top tech writers. This week's pick is a new way to keep your car clean.

Jaguar Land Rover is testing an in-car ventilation system that uses germ-killing ultraviolet light, said Jake Holmes at CNET. The technology, called UV-C light, would be integrated into "hidden vents and ducts inside your car's dashboard" and would be more effective at sterilizing the cabin air than the ionization systems that exist today. UV-C light has been used in hospitals to sterilize surfaces by neutralizing bacteria and other pathogens, and Jaguar thinks "your car could be doing more to keep you healthy."

The company has a partnership with Google's sister company Waymo to develop autonomous vehicles for a ride-hailing service, and has launched a "subscription" car-sharing service in the U.K. A car with the technology could prevent illnesses from passing between passengers and make riding in shared cars more attractive.
