The Mach E just shouldn't have been following the way it was. Autonomous systems need to maximize their road information, not follow social trends (i.e. not follow closely on the highway at the sacrifice of visibility)
That can be true, while also being true that a moving car in front of you can better see an obstacle while obscuring it from the car behind. I’m just saying that the car in front that avoided it was in a different visibility situation to respond than the following car.
