1. the entire point is to test the emergency braking features which are active by default.

2. I would definitely prefer a false positive where tesla brakes for human shaped balloons crossing the street than the potential for plowing through a human because of a bad radar reading.

this video is obviously not unbiased but here you can see a Tesla plow through a dummy that is obviously not made of balloons https://youtu.be/tkAtRw51jGY?t=81

> 1. The test may be fake, and Tesla driven manually.

The second video had in car footage clearly displaying a visual warning and playing a collision warning sound. Because of concerns over phantom braking, these can be overridden by the accelerator pedal.

I wouldn't call it fake, but it is exaggerated.

Car radars aren't sensitive enough to pick up pedestrians anyway. They're useful for detecting metal vehicles, and pretty nothing else. If you mean lidar, dummies are not transparent to those wavelengths.

This is not true. Car radars do pick pedestrians, but some car radars (blind spot for example) filter that out in post processing.
