Dockspock, Police drivers are pretty good. British Police drivers are among the best in the world. I'm not sure why you seem to disagree with this? Maybe you're referring to ordinary beat bobbies, who have a simple response training course in order to get their permit. I was, and am, referring to trained traffic officers, in high performance vehicles. Not bobbies dotting around in astras.
Ladybirder, I take on board what you say, and I'm not trying to be argumantative either, I'm really not. But the speed is not the problem. The problems lie in drivers who either aren't trained enough (some aren't at all in the case of un-licensed drivers) or are too busy faffing around with their radios or phones to notice whats going on in front of them. Here's an example. I had cause to stop the traffic on a country lane about 6 months ago. Picture me, in a car with flashing lights on the roof, slowing down from 60 (the national speed limit) to a standstill over about 150/200 yards or so. We're not talking about an emergency stop, it's fairly gradual braking, as I'd noticed a couple of sheep in the road ahead, just stood staring at me. As I got close to them headlights flashing, they were still staring, but not moving. So, I got out, and shoo'd them (if tha'ts even a word) off the road and into a field through an open gate. I then heard the screech of tyres and noticed behind me that a vectra was hurtling towards my car sideways. It stopped just in time, but left 40 yard skidmarks up the road.
Now the stopping distance at 60mph is 73 Mtrs. The portion of this that's actual braking distance is only 55 Mtrs. So that gives the driver 18Mtrs to think about what she needed to do to stop (ie: press the brake pedal). Now if she were looking at the road in front of her, she would have seen me, on a long, wide straight road which it was, from at least a mile away. So why did it take an emergency stop, a loss of control, damage to her vehicle and the road in order for her t
