Have only just skim read most of this so apologies if its been cleared up...
Is that the only light she had..? The one on her backpack pointing to the stars? Not ideal if it is, though I accept it could be that her rear light is "drowned out" by the street and other lights..?
The first overtake wasnt anything like the defensive driving he needs in a city like London imvho.. If he drove like that here I can assume that he'll hit another vehicle or street furniture sooner or later. His second pass was imo deliberate and intimidatory, as I said on the youtube comments he prolly assumed he'd got away with it not realising the rear facing cam.
In my experience I find cyclelanes like that impede safer overtaking of fellow cyclists as drivers will come far too close to begin with. On an unmarked regular road drivers often slow down behind you to see what you're up to so you can whiz past other cyclists much easier and safer. Drivers expect you to remain in the confines of the cyclelane and not exit it for any reason....
The CSH scheme could have seriously been improved if they closed off one or two of the CSHs to all non-motorised except buses, taxies, residents and delivery vehicles. Such a radical approach would never be done in the UK though, even if it does stop the jossling and the other problems we all face. I dont think drivers need the shortcuts and the rat runs in reality - as the vehicle is doing the work for them.
EDIT:just remembered something. I knew a scaffolder on our site who had a guy get out of his car like this at him (something to do with the numpty overtaking him forcing him and the scaffold truck into a ditch and hammer his horn). So this bloke has hammered on the brakes and got out shouting at the scaffolder lad. He said "I thought the guy was gonna hit me so I went first" Knocked the guy spark out and phoned the Police.
Apparently this numpty had done it to others and had a history of aggression. Scaffolder got let off the punch as it was self defence but had to go to court as a witness. Dont know what happened to the numpty.
