You are correct, but that doesn’t mean I can’t speculate about it.
The ability to do photosynthesis is widely distributed throughout the bacterial domain in six different phyla, with no apparent pattern of evolution., according to this random paper I found on the internet (I’m not a biologist either).
What I can glance is that photosynthesis has (probably) evolved independently 6 time in Bacteria and 3 times in Eukaryotes.
Plants evolved to photosynthesise after photosynthesising bacteria already existed for billions of years.
(But then we have to also acknowledge that multicellular life evolved like 25 times in Eukaryotes, and the Eukaryote - aka Mitochondria-“Powerhouse of the cell”-haver- is the real big step as it only happened once to our knowledge).
This bike lane is on the left side, but the bike lanes in the rest of the city are on the right. Someone then thought the best way to connect them is to have them cross 2 streets to get to the bike path leading to the right, and from there take 2 left turns if they want to go left, which also has a separate lane for right turns - just for the cars, of course, so that is another lane bicycles need to cross.
So, depending how the traffic lights work, bicycles have to wait up to 5 times to do a simple left turn. The traffic needs to flow after all, and traffic just means car traffic to some city planners.
