Elon Musk and the Alliance of Automobile Manufacturers want to replace side and rearview mirrors with cameras writes Ariel Bogle:

• Having cameras instead of mirrors would increase the efficiency of cars as side view mirrors currently create a lot of drag.
• Image processing features such as infrared and thermal imaging sensors could also be added to improve safety.
• It seems the best place to put the image from the cameras would be on the steering wheel – keeping the image in the driver’s field of view.
• This could be expensive. Adding cameras in the back to help those reversing their cars costs at least $45 per vehicle.
• Regulators may feel that it creates more safety risks than it fixes – after all, what if the camera breaks?
