Louisa - about my comments - when you say I should.. "...consider the frustration you cause by slowing down traffic through busy parts of cities..." ..on my bicycle I simply cycle past traffic that tends to be stationary most of the time in busy parts of the city. I tend to pass vehicles and leave them behind as a result. I do not add to their journey time. When I drive my car I get stuck in traffic and see bicycles cycle past by me (which I have to say I do not consider a problem). And about your comment that I am.. "..gloating by suggesting cyclists are amongst the most aware on the road.." It is merely my impression based on my experience of both forms of transport. On a bicycle you are more exposed to the environment around you - and therefore react accordingly and your senses are heightened as a result. I have three bicycles but I also love driving. I have a very enjoyable and cherished, rare, open-top Italian sportscar. It is a reasonably fast car. But I know for a fact it cannot compete with a bicycle in getting through London traffic as quick and efficiently. I would certainly therefore recommend Parsley commutes by bicycle. It would seem to me that mopeds and motorbikes are also a good way to commute - but I have no experience with them so cannot advise accordingly. Hope that clarifies. Sorry to others for moving off topic slightly. Anyway must dash - Matron wants to dry me off with some warm, fluffy towels.
