The acceleration your car experiences in an accident is an order of magnitude higher than anything your car ever experiences in everyday use, making the control system very easy to engineer - something like anything over 20g's and it pops (the algorithms take vehicle speed into account too for a varying threshold and probably use jerk.)
In that video where the rider was hit from behind, there was very low relative change in velocity of the sensors in that helmet - no direct impact spike - and its on par with the same levels of acceleration you would experience in everyday bike riding.
You can easily have 20g impact when you speed over road bump.
The accelerometers in your car are bolted to your 4,000lb frame, riding on dampened shocks and rubber tires - you will never experience acceleration anywhere close to what you would in a frame-on collision.
You will easily experience that, just that energies involved are minuscule compared to collision. The mass of your car frame is irrelevant, shockwaves still propagate through solid bodies. When someone slaps your face hard, that can easily be 100s of Gs without much ill effect.

No, it was not easy at all with the cars. You can easily have 20g impact when you speed over road bump.
Also, I'm sure in the 5 years they spent on product R&D, the concerns that came up to you in few minutes here were raised too.

They don't have a shipping product yet.
