No, you do not need 5G for autonomous vehicles. The design is meant to be autonomous, without needing outside control. We need to keep it that way.
The DARPA competitions that started the autonomous vehicle movement 20 years ago, insisted on no outside control.
Not what I understand from attending a presentation by someone who’s involved. It’s one thing operating a single autonomous vehicle, but operating a whole fleet in the same area apparently requires huge bandwidth and the U.S. is not up to it technologically.
China is, unfortunately, and they are taking the lead in this area—the speaker said they have been advocating that the U.S. get a move on so it doesn’t permanently lose the lead to China.
It may be true that the systems will be able to function without outside control, but it will also be true that government regulations will require that the capability for outside control will be provided in those systems.
