A Tesla or other self-driving car may be out of reach for most drivers, but there's a novel add-on alternative from a familiar name and it costs less than $100. General Magic, which was a player in the Apple Newton days, has reinvented itself and is Kickstarting a project called Safety Lens. The hardware and app offering makes heavy use of the iPhone's camera to detect road signs, cars, lanes, and more. Combined with the windshield mount and your iPhone (in landscape mode), you can be alerted to important updates using visual indicators, sound effects, and text to speech.
