I've never heard about such an experiment, but I agree that it should be tested. I feel like I see false dichotomies every time this subject is discussed.Re radios: every rider had two way communication with race control, not with their own cars, would solve the safety issue, while removing the riding as robots syndrome. Has it never been trialled?
Several variables to take into account:
Access to Radio Tour?
Radio communication between riders?
Allow the team car to listen in?
