I’ll be the rule prover then…personally I find balck cabs the worst (had one ram me intentionally on whitehall in no trafic, just for the sheer pleasure), then buses, then addison lee. all are tryng to kill you, the 3rd are consitent so preducable, the first 2 are very variable so far more scary.
lots of good advice above. just be visibule, lots of lights etc, ride sensible, clear signals, eye contact, assertive, scowl and scream if you think you’ve been missed. don’t go up the left of ANYTHING and especially not a lorry. watch out for muppet cyclists as much as any other road user. enjoy the adrenaline!
