We don't need to encode "cars must turn right" in the data, since that's implicit in the restriction on the Tottenham Crt Rd way.
And that restriction data is on there. We have "motor_vehicle:conditional=no @ (Mo-Sa 08:00-19:00)" and also "bus=yes" on https://www.openstreetmap.org/way/299682133 . That's been in the data ever since it was a proposal, thanks to MacLondon.
I wondered about adding bicycle=yes, but that's not needed as a cancellation of motor_vehicle:conditional since bicycles are not a motor vehicles.
So I think we're all good. Anything left to fix?
