Only problem with the guy's disappearing act is that he's flashing his high beams after speeding away - it's not very hard to see where he's going.
What other traffic sees could sure be an issue, like the idiots who drive in rain spray with their lights off; only takes a second at speed to miss seeing something like that.

Back in the day, a tail lamp kill switch was something a street racer might do, though the headlights would betray the car's location.
Funny side-story: in my 20s, there was a guy who'd park his Impala to guzzle wine or smoke pot, but he'd always rest his foot on the brake pedal.
So, 4 tail lights blazing away...until one of the neighborhood guys rigged a kill switch rather than get caught when accompanying him...
