Ouch...I just fell

eeehhhh Ouch.

As you said very lucky you weren't on the road.

I know you weren't on the road, but anyway, it seems to me that roads in London seem to be coated in stuff that makes them more slippery - loads of painted lines everywhere, drain covers, man holes and those stupid metal squares that are on either side of pedestrian crossings embedded in the road.

Also remember roads are bussy in London. Most vechail do not perform 100 % combustion plus many burn all be it a little amount of oil. This of course comes out of the exughst pointed down on to the roads. On less buussy roads this does not matter unless it is dry for a long time where the oil gets to build up but then when it rains it is initially very slippery until the road is washed off, very bussy bussy roads just get a build up of the oils very quickly and hence slippery roads. Another reason for Londons slippery roads.
