there's a series of roadworks to do with the crossrail station at farringdon that narrow the road to one lane for about 200m. The guy on the bike was "weaving all over the shop" (trans. riding in primary as the road is too narrow for overtaking).
At least, I assume he was riding in primary instead of weaving about, as I was at the traffic lights before he got there, so didn't see what happened, only heard the passenger shouting out of his window. The cyclist dealt with it so calmly, I'm assuming he was just riding in primary, like most bikes do on that stretch.
The cherry on the cake was that the lights were red anyway, so it didn't delay him at all. Can't remember the driver saying anything at all.
