Hey everyone, I might be driving down to London tomorrow and I'm seeing a whole bunch of Ubitricity chargepoints on ZapMap - they look like just normal residential parking spots. Has anyone here used them before? Are they easy to use? Do I need any sort of card, or can I just get an app like with everyone else? Also, any idea how likely it is that I'll pull up and the single space will be taken? Should I make a list of the 5 or so nearest to my destination (British Museum) just in case?
