I don't intend to get into an argument with you regarding this topic, but as you have probably never undergone the level of training that I have (unless you can tell me otherwise) in fairness you are unable to make an informed comment on the skills of trained police drivers. I would never endanger other road users or myself for that matter, and that is the whole reason for undergoing the intensive course that we do, in order to become a safe driver.
I'm sure that if you ever had to call on any of the emergency services, you would expect them to get to you as soon as they possibly could in the safest quickest way, if this requires the trained driver to exceed the speed limit, and drive on the wrong side of the road, then you can rest assured that they would do that in a safe manner when, and only when it was safe to do so, crossing red lights, when you have established that all other road users have seen you and given way in order for you to proceed safely towards your destination. On the other hand we can just amble over making best speed and get to you eventually.
