I feel the more segregation between Cyclists and motor vehicles the better. 'Convoys', Cycle training etc are fine but not everyone is able / wants to become a very safe cyclist. I live in London and have cycled many years but i still make mistakes or been in sticky situations (close overtaking). We all know there are a lot of very bad drivers out there and no cycle training is going help people anticipate them or the situations they cause. I believe that motor vehicles and bicycles shouldn't share the same road space. When i cycle i have to be really aware of safety at all times and confident in my abilities to be seen and understood by the drivers of cars, buses, Lorries etc. To build up this amount of experience takes a long time and frankly a lot of enjoyment out of cycling. I know some people enjoy commuting like this everyday but for most people, including me, this is not enjoyable or a very safe way of cycling. In Europe (particularly Holland & Denmark) almost anyone can hop on a bike and be 99% sure that their road space will be respected and they will be safe. This is total cycling.
