It would be a good idea for driver training and the driving test to include some theory and practical content to raise awareness of cyclists and the fact that they have just as much right to be on the road as any motorist, pedestrian, or stray cat or dog, and how mutual consideration and understanding between road users would help improve safety.
There is some inclusion of such in CPC training for HGV drivers nowadays (personally I find them amongst the most considerate drivers on the road, if a car is a potential lethal weapon, a lorry is a potential ballistic missile in comparison, and most HGV drivers seem to take their responsibilities very seriously in my experience), but why not car drivers, taxi drivers, police drivers, etc?
