I don't think i personally would have took the ASL if there was a singular car. It does irate drivers if they feel you have pushed in and what is the point in holding them up when they only then have to overtake you later on, and probably do so quite impatiently bcoz they are pissed off at you. I only filter to an ASL when there's a queue and i know I'll miss the next round of lights. However, the cyclist did nothing wrong other than confront an impatient nobber. Said nobber broke the law throughout. He should be prosecuted for entering the ASL which he clearly did illegally with no mitigating circumstances, thus causing the issue, and then he should also be prosecuted for assault. The cyclist didn't break the law (altho he might have broke the speed limit trying to catch him up to finish the conversation which, if you watch again, the car driver clearly started )
