Riding to work this morning I popped out at St Leonards just behind Mr ARobComp. We wound up chatting all the way through the Meadows, slightly overlapping, but still both in the cycle lane, heading past the queueing cars, and generally having a very relaxed and welcome chinwag.
You can obviously do this walking if you happen upon someone you know, but in a car you are just completely shut off from the outside world. See a friend and the best you can manage is a little flash of the lights, or a toot of the horn. It was so nice pootling in (well, Alex was pootling...) like this.
No real point to this, just another example of how mcuh more friendly cycling is.
