What is stopping you

As humans, the sense we rely on the most is sight. Of any sense impairment, blindness is considered the most challenging one and for good reason. This holds true for most of our daily activities and driving is certainly no exception. So if you want to drive a car from a remote location you need to be able to see the vehicle’s surroundings. If you were doing this with a device in your close proximity you might use an HDMI cable or your personal WiFi. However, AVs are moving over great distances and must rely on whatever public network is available.
