The first vehicle into a space has right of way: in the event of a tie – the biggest, most phucked-up vehicle wins. If one vehicle obviously belongs to a party official then the same rules apply, but the emphasis falls on the second vehicle to avoid contact. This makes taking junctions at speed pretty hairy.
Stay clear of the bicycle/motorbike/e bike lanes, and instead slipstream the larger traffic. You’ll be the only pedal power playing with the big boys and as long as they can see you they tend to show respect. The major exception to this are some of the bus lanes – they are a license to speed, can quickly become single lane channels with no escape route. Know your route kids.
22:00 is a good start time, the traffic has died down to something approaching lite.
