At 1.3 seconds, and with as many false-positives as it sounds like the system has, I don't think a warning would have helped.

No, it would probably take a large part of that time to even react, especially if you are looking at a screen.
However, if the safety driver was trained to brake immediately upon warnings it could have worked quite well. But that would negate the removal of e-brake actuation.....

If the car cannot use emergency braking it could at least decelerate. It looks like some hack where the engineers just commented out the code for brakes and left decision to the driver.
>2 In Uber’s self-driving system, an emergency brake maneuver refers to a deceleration greater than 6.5 meters per second squared (m/s^2).
So, Uber's self-driving system has command to brake normally, but it cannot "slam" the brakes. The other system from Volvo's is deactivated when Uber's is working and cannot brake at all. Thus, since Volvo's is deactivated and Uber's won't brake if it judges that a deceleration of >6.5 m/s^2 is needed, it turns out that in automated mode, the car actually lacks the ability to trigger emergency braking at all, hoping instead that the driver will somehow notice. But in a sadistic twist, no warning is given to the driver at any moment that they need to slam the brakes.
