My eldest child passed with 12 minors, most of them being overly careful. I taught her to give plenty of clearance and to wait for ample gaps in traffic when pulling out of junctions.
There does seem to be a little bit of backlash from teaching your own children with their own car as opposed to using a professional instructor.
My second child I mainly taught him, but he had a number of erm 'professional' lessons. The biggest difference between my teaching and the 'Pro' was, the approach to junctions, the 'Pro' wanted my child to keep rolling when pulling up and out of junctions- albeit slowly.
I thought that was so stupid and dangerous, it gives little chance to observe properly, to see if its clear to move out of a junction. We adjusted his driving to creep out on left turns only and to stop fully for right turns.
The other point we picked up is called making progress. The examiners and instructors, expect you to quickly pick up speed, almost rapidly between difference speed limits and not wait for (my opinion) safer gaps to pass parked vehicles or go around cyclists etc.
Over the years I've taught relatives, friends, partners of children, my wife. Overall, no accidents or convictions from my children or their partners and very few incidents in over 25 years of family driving, so I take it I'm doing something nearly right.
The 'making progress' thing is something I do not agree with, if fast driving is encouraged, then is it safe?
I can understand the reasons, but surely better to drive appropriately for conditions, rather to emphasis making progress.
I passed my test back in '81, more than one test required, one had to be abandoned ( not through my own fault ).
I recently took my motorcycle license and passed first time this year, , not normally my style of driving, but I made progress as advised.
Actually I am pretty pleased that I have maintained the pass standard with 40 years between tests,, riding motorcycles , requires a higher standard of awareness ,I think than driving cars, and it has improved my driving.
Perhaps 40 years experience does that,, teaches you patience with modern traffic.
Mind you, seems to me that once they have that pass certificate ,it's lobbed out the window ,so to speak, given the driving standard I see every day.
