We are one of the area's that are currently trialling this and for once the DSA have got it right and it's a good idea for the independence bit. But as an advanced driver instructor and independent examiner I'll tell you what the new driving test is a joke I could train a chimp to pass it within 2 weeks, talk about dumbing it down, based on advice from the government the DSA have been told to up the percentage rate for first time passes so how do you do that? Improve driver instruction or dumb down the test? you guessed it they have done the latter.
My daughter is currently learning to drive and what an experience that has been the quality of some ADI's is absolutely shocking so much so that after we had a disaster with the first one I insisted the ADI's we looked at drove me first, I was open in what I do and 3 out of the 4 of them refused the 4th a nice woman instructor drove me no problem and was first class it was the only way I could ensure my daughter was receiving the correct instruction.
As Lil Smartie points out basing competence on hours of instruction is ridiculous, I know people who have literally had hours and hours of tuition and years after passing their test still can't drive I also know of others who have had no lessons been driving on the farm from 14 took their test on their 17th birthday and passed first time and made excellent drivers.
The way out IMHO is LOWER the age at which you can drive and then base it on hours, toughen up the test to include, rural, motorway and driving in the dark, OK you would have to do it in stages but the roads would be a safer place for it.
Also ADI's should be more thoroughly tested to weed out the cowboys and give the profession a better image
Sorry rant over but I hate seeing people ripped off for very poor tuition
