I think you need to put a little perspective on this.
This guy is an advanced driver. What does that mean? First off he'll have gone through the following courses as a Bare Minimum.
Basic driving course - 2-3 weeks dependent on force
intermediate driving course - 2 weeks, night driving, skid pan
advanced - 4 weeks, double white line overtakes, snap overtakes, night driving etc.
Thats a minimum of 360 hours of intense specialized training. How many does a normal car driver have? 10-20?
Thats a minimum of 9 weeks driving at least 8 hours a day under continual assesment, with instant fails at any time on the course. The courses are mentally exhausting. At the end of each drive usually an hour long, you are debriefed and virtually every corner, overtake, safety aspect etc is gone through. Can you remember every detail from a drive you do for an hour? When they are taught to drive you are taught the system of driving, which teaches you to take in a number of things but is based around and above all safety. When you drive it you are reading the road as far ahead as you can see. That doesn't mean the bit of tarmac in front of you, but if you can see the tops of street lamps over a mile away over the top of a hill you are taught to interpret them eg a roundabout coming up etc.
After that comes constant assesments during the working career, retests, refreshers, further courses such as pursuit, tactical containment etc. Have you ever sat in a car with someone whose a numpty driver who you don't trust? You sit there with your foot going through the floor where the brake pedal should be and you crap yourself. Sit in a car with one of those guys driving and you will feel totally confident and struck by the air of calm thats in the car. Listen to a commentary from one of these guys driving in a follow at speed and hear how calm it is. You can tell an advanced driver from a normal patrol car driver. They are calm and clear and concise. The untrained driver normally sounds like they are on helium, don't listen to whats being said and repeat themselves over and over again.
So when it comes to the crunch, your child gets abducted, a police car gets behind it and gets on the motorway and gets to a speed of 160 mph. Now the helicopter is scrambled but its going to take 5 minutes to get overhead. What do you want that police driver to do. Do you want it to be a driver whos been trained to do that and is as safe as possibly can be?
Testing out the car? Its a fair point in principle as every car drives differently. The cars they use are checked every day eg oil water, tyre pressure etc. They do all handle differently and all have their own little idiosyncrasies. Not to much of a problem at 30 mph, but in a follow at 100 mph it makes a big difference.
Every time those blue lights go on every individual has to take a decision. Is what im doing justified, is the way im driving acceptable and safe? Believe me i've seen a lot of policeman end up in court for various accidents or offences that happened during their work when involved in a follow. Some have been absolutley justified and some seem to be the higher ranks covering their arses. As for this one. Well his case has gone through the judicial system and a district judge has passed the judgement on him.
Personally i think that the force would appear to be to blame for their policy and i think he went about it in a stupid way that has not gained any support from the public. In my old force any training drives or familiarisations had to be booked as such and you had to have a senior driver with you.
As for the moustache. Totally and utterly unacceptably silly
