Trouble with deliveries - Unsafe

Here are some still takes from video. On Saturday 8.50am I had a delivery. According to the council this is okay and vehicles are allowed to wait on the double yellow lines. However in practice this now stops all outbound traffic as the lanes are too narrow for traffic to pass safely. Please note the van is not that big compared with some and look at how close passing cars are! Just imagine this at 8.30am on a Tuesday for example. The whole of Duffield Road northbound would grind to a holt. In fact this is likely as I am having a John Lewis delivery next week. This scheme does not work!!!
