It's not theoretical, and you don't need them to talk to each other to reduce accidents. Nor is the tech you mention necessarily unique to EVs. There's evidence already that the safety features shipping on modern cars, including collision warning, avoidance, cross traffic alerts, etc. are already helping to reduce accidents. Where EVs can help here on safety is encouraging people to drive more slowly (due to efficiency concerns) and also advanced in motor traction control that is not possible on an ICE vehicle. The rest is not unique to EVs.
