Well, I can't disagree with the reasons, but as someone who lives outside the M25 this means I lose a really handy way to get home when I've had a drink. Ah well, I'm supposed to have given up anyway :-)
I can actually walk that in under an hour if I need to.
I've found myself in countless situations where the walk is maybe 10-15 mins longer than any available public transport (Uber included), so I've saved myself the money and taken a hit on a little bit of time.
