As suggested by Gembo on another thread I think it is a good idea to share stories of good and courteous drivers as it is all too easy to get caught up with the idiots who try to spoil our enjoyment of cycling.
Here is one this morning- I need to turn right at the roundabout at Leith Street and it was blocked on my right hand side as I approached it this morning. As I rode on and signalled left to leave it, a bus and a lorry drove forward and stopped, blocking my way out. I started to go round the back of the lorry to discover that the lane beside it was empty and a taxi driver was approaching. He immediately stopped and waved me on. I thought that was nice. He could easily have just swept through and ignored me. I said thanks AND waved just to make sure!
