  1. That doesn't look anything like a car, person, or bicycle. The Mobileye camera system is smart about what it sees, and this looks like none of those.
  2. Styrofoam is not reflective of radar waves. What they built themselves is a wall of stealth material. They needed to coat it with something radar reflective.
If you watch demonstrations from other car manufacturers, they use foam blocks covered in cloth or vinyl inflatables with pictures resembling the backs of cars.

Poor test. They need to step it up and try again.

Also, it's important to note that Tesla hasn't said whether pedestrian detection is enabled. Please, don't test it on people like these people incorrectly and terribly did with a Volvo.

Wonder what difference it would have made if they wrapped the foam with aluminum foil or a metallic paint.

It would also be interesting to see how a 2015/2016 model year Volvo or Mercedes with similar sensors can handle this situation...

Seems when the car is in autopilot mode and following a car, autonomous braking is solid.

Bjorn took that video down, probably because as people pointed out Styrofoam is pretty much air and invisible to radar.

If styrofoam is essentially invisible to radar, then I see how the test really didn't prove anything. I've witnessed the TACC in action, but was just hoping to find some benchmark videos showing the effectiveness of emergency braking, then came across this video via google.
