Tapping simpler technology, a Romanian teen has produced a way to deliver a self-driving car at far lower cost than the big players in the field have yet managed. Ionut Budisteanu's system uses a low-resolution 3D radar to recognize larger objects and webcams to detect lane markings and curbs. Artificial intelligence technology then determines the most safe route for the car to follow. The $4,000 innovation won Budisteanu the Gordon E. Moore Award -- and $75,000 -- in the Intel International Science and Engineering Fair.
