Not Mercedes finest hour TBH. Though I still think the idea is far better

Agreed. Certainly better than a double-decker. I miss them, even though I DO like the Borisbus.

But I too have not been on a Borisbus in the last few days, so I cannot tell how hot they are.

I have been on the front upstairs of a standard double-decker 280 bus to Sutton with the sun streaming in the unopenable front window and being reminded of various tortures at Abu Ghraib/Guantanamo.
