Its all over the net now the reason why it failed to work. Something to do with the fact that it was in an underground car park/tunnel The system doesnt work in such conditions plus no one would use distronic plus in an underground car park/tunnel anyway
We have discussed it before, but I think it's worth pointing out that the car did slow down significantly, thereby minimising the damage. No a total success, but there is arguably some merit to the system.

Incidentally, the black car is the one doing it 'properly' The silver car (not in this clip) is the one where they cheated.
