(Reuters) - Tesla Inc has dropped radar sensors from its semi-autonomous driving system, Autopilot, raising concerns over the safety of the camera-only version, Tesla Vision.

Tesla aims to make the driver-assist system fully self-driving, and many in that young industry are skeptical that a vision-only system will work, saying such systems face challenges in darkness, sunny glare and poor weather conditions.
