Ah well done, yours seems a lot neater than mine. I think segregating the buses until the last possible second just helps to keep traffic flow high, but also the fact it is two lanes means there isn't much backing up around the whole roundabout, which is the main problem with this level.

I do not fully understand how it works, but it is brilliant.

Awesome, both effective and never seen before.
