Before giving these students an A, I'm going to have to ask that they replace the cones with their own cars. That's where you draw the line between "I think this will work" and "I have complete confidence that this will work". It's analogous to if I were a welder working inside a giant propane tank. The guy with the gas meter can swear up and down that it's safe to fire up the torch, but I'm still going to insist he stand in there beside me when I spark up. Besides, it just makes better video. It's not anywhere near as impressive if there's nothing on the line.

Especially they confidently tell us, that the system is accurate to two feet. Sadly two feet is the difference between parking ok and damaging both cars significantly (i.e. you'll have to at least fix your bumpers.)

If you look at the tire marks on the ground it looks like they ran this test quite a few times. I wonder if they ended up just moving the cones where the car happened to stop and then took the video.
