I hate the Tube...
It may be efficient, but seriously, it's not a good place to be on when you're an Aspie with personal space issues. I very nearly freaked out many a time when I was packed in like a sardine in the Tube. Like as in started flailing out and hitting anyone nearby freaking out. Seriously.
Still, I navigated the Tube with more ease than my fellow traveller during that trip. I can read a Tube map and correlate it with a London map so easily it isn't funny.
"What have you been doing since you stole that antique TARDIS of yours, since you first landed on Skaro? Shouting 'Look at me!!! I'm not fighting a war!', while you battle the Daleks all the way through space and time."
