Re: The reason that the Max series need MCAS
Likewise my current car has a collission warning system with emergency braking system. It leaves things much too late IMHO, I have never tested the system, because I just don't trust it to stop in time. At the most, it looks like it would lessen the impact, as opposed to avoiding the accident altogether.
The point is that you aren't expected to trust it to stop - it's there if you forget to stop for some reason.
