It's definitely Avtovo; you can see most of the name in the cap.
I haven't seen any red cards, but the gorodki is the RB? And since they take taxis to the circus, I have no idea what the bus is for.
It doesn't look like the bus is even used by the teams as everything is too close together for that. I can definitely see how the leg could work out like this:
1. Teams go to the Church first and wait for it to open (some teams may get lost or misdirect others between the PS and the church)
2. They do the RB at Gorodki all arriving at similar times
3. Some teams take longer than others there
4. They do the Detour at the circus
5. The Pit Stop is somewhere closer to the circus
