Wonder if you could test ACC using a heavy drop cloth with 2'x2' panels of foam insulation like this:

The sheathing should be dense enough to reflect some sonar, the tarp+sheathing would be visible to the camera. I'm gonna have to research how the Tesla owners tested their ACC safely (and not with a wall or car).
