They’re talking about avoiding legal liability, not about actually doing the right thing. And of course you can see how it would help them avoid legal liability. The lawyers will walk into court and honestly say that at the time of the accident the human driver was in control of the vehicle.

The plaintiff’s lawyers would say, the autopilot was engaged, made the decision to run into the wall, and turned off 0.1 seconds before impact. Liability is not going disappear when there were 4.9 seconds of making dangerous decisions and peacing out in the last 0.1.

Encrypted data, all classified data that is transmitted over commercial networks must use approved encryption tools that conform to specific encryption standards.

You’re partially right, stationary objects on the side of the road will have a different Doppler shift than a stationary object in front of the vehicle, items on the side of the road can be filtered. Cheap radars with low sampling rates will not be able to distinguish as their Doppler bins are fairly large.

Radar would not detect a Styrofoam wall either the return from Styrofoam is extremely low. Radar also can not distinguish elevation differences very well so an overhead road sign can be mistaken for a stopped vehicle or a stopped vehicle mistaken for an overhead road sign.
