Road.cc highlights a very salient piece of CCTV evidence in its piece.

QUOTE:
"CCTV footage revealed that Northcott ***illegally*** (emphasis mine+) entered an advanced stop line – also known as a ‘bike box’ – at a junction. When interviewed by police, he admitted that he did this regularly to avoid being “swarmed by cyclists.” END QUOTE.

+ "Illegally" entering the ASL would, of course, mean that he was caught on CCTV driving into the box while the traffic light was at STOP or red as practically any other situation would be legal.

He even ADMITTED regularly driving into the ASLs illegally, in court under oath!
