might be a lot more civil to each other if it was mandatory to pass tests in both cycling and driving if using the road, whether you are a cyclist or vehicle driver.
Of course there would have to be exclusions for people unable to cycle or drive for any reason (a simulator perhaps). However, with the focus on green living and the sheer increase in road traffic on our narrow city roads something has to be done. We cannot divide up the roads there is simply not enough space, we need to be able to share them and understand all road users needs as well as our own.
