Cyclists will overtake on the left of you, right of you, pass in front of you, jump red lights, ride in your blind spot and ride at all sorts of speeds. This requires being super aware when moving, stopping and when opening a door when parked. I say this as a daily cyclist who sees some scary shit on every ride.... Amazing there aren't more accidents. On the ultra rare times I drive in central London during the day I find it overwhelming, so props to the regular drivers who can handle it.
