> but watching the video () of the test shows that the car did not warn the driver
The warnings occur when you look away or don't touch the steering wheel for a while. Not saying that Tesla is without error (it isn't), but just clarify what the warnings are for.

No, they serve a very specific purpose -- (attempting) to ensure the driver is at the controls and paying attention.
Don't confuse the FSD attention "nag" warnings with collision warnings. The collision warnings will sound all the time, with and without FSD enabled and even if you're not looking at the road. If you don't start slowing down quickly, Automatic Emergency Braking (AEB) will slam on the brakes and bring the car to a stop.
