Safety-wise it's better option.
Breaking vs just rolling without working brakes.
And I really do not like trend of making brakes drive-by-wire instead of mechanical just to (presumably) save few pennies...

I'd consider that autonomous vehicles should apply the brakes if they find themselves in an uncertain situation as reducing speed is going to minimise any impact. However, this was being driven acoustically and the handbrake shouldn't have been applied automatically by the power running out. At the worst, if a handbrake fails and can't be used, you can always shove a couple of bricks under the wheels to stop the vehicle rolling.
The problem about “yeah well they should have left space” or “they should have responded perfectly to a car that’s suddenly braking” is that it’s not realistic to the real world. It’s not a least-surprise event.
