The traffic light thing ís indeed a thing but then there is só much that can and thus wíll at some time go wrong whatever you do.
I was run into by a van full of mentally handicapped while waiting for two elderly on a pedestrian crossing.
I sáw the van coming; knéw it was going to clobber me but what do you do?
Managed to veer past the elderly couple and crashed on the elevated roundabout.
Incredible mayhem followed with panicking passenger running about screaming.
Moral; would have happened clutch in or out.
I lived in the Dutch ´Randstad´ and commuted on the motorbike. Sidecar as well depending on where/when I needed to be. Effin´ un-be-lie-vable what motorist get up to.
You MUST ride in the conviction that NONE will register you.
My life´s story has an apt prequal btw.
My mother to be was dating my dad because he was a bit of a bad boy. She was not really serious, a bit slumming with that as he was from the bad side of the bridge.
One day early morning he was riding to work and a car driver made a U-turn. Yes the classic ´did not see you´.
Him in the hospital her dad said ´...and nów you had better visit him dear!´
It cemented the relation.
Recovered he started scootering to work and when I was 4 he sometimes dropped me off at kindergarten with it.
It is not in collective family memory what brand/type nor do photos exist.
Back to clutch in/out and traffic risk, I would like to point to a wonderful book for motorists which is gold for bikers/scooterists. It is all about anticipating:

Never mind the price of th´ñis one; they pop up dirt cheap too. Very much worth a read.
