Driving into work in Glasgow from Stirling just now, was interesting to say the least... -11 at my house in Stirling, with no variance to speak of all the way through to central (yes central) Glasgow, where the temp in my car is showing -10 !! My car struggled with the temp, the accelerator idle speed was stuck on due to the severe temps, which was a bit hairy until I stopped and turned off the engine. Snow I can deal with, but these temps are absolutely ridiculous, and it will only get colder....
