Sadly I hear a lot of snippets about other instructors still teaching methods from the 1930s, like parking in gear, using gears to slow the car instead of using the brakes, driving on sidelights in the dark, stop at every junction, signal off mini-roundabouts, even if already leaving, etc. To me the most important thing is to get the learners to think, not just repeat.
I've met a lot of instructors who will never take a learner on the motorway. Worrying, if they think they are at test standard, they should be capable of motorway driving. If any learner is not capable of motorway driving, they are not test ready. I will never take a learner to test that I would be unhappy to meet on the road the following day!
Personally I (almost) always park the car with the handbrake on and the gear lever in 1st or reverse. Not because of any particular safety reason but simply out of habit born of driving Mk1. Escorts and Moggie 1000s in my very early driving days. As I think I mentioned a few posts ago I do mention it to pupils by way of general education but don't get them to do it on lessons or test. I think the hope is that if they do have to park on a steep hill, at some time in the future, they will remember to take that additional precaution.
Since I started teaching in,1987, the motto has always been "Gears for going, brakes for slowing" but I do remember an animated conversation about 10 years on here where several members from hilly, rural areas, such as the Lake District and parts of Wales and Scotland bemoaned the fact that very few younger drivers seemed to know how to use the gears as a method of controlling the car, either on hills or when driving round bends; and they were all fairly young themselves.
The fact remains though,that the very people who should have had the best interests of learner drivers at heart, their parents, are often the people who come up with quotes like: "I've taught him/her to drive, can you just let him/her take the test in your car and show him a few tricks of the trade?"
Or, "Of course you only start to learn to drive once you've passed your test"
Most parents want to spend/want their children to spend about £50 in order to pass a driving test and plenty want to have a discussion about the finer points of driving that they think they know, yet you can't teach everything a new driver needs to know during the course of 25 to 40 hours of tuition.
Pass+ exists for that purpose, as do the IAM and RoSPA.
I haven't yet taken a learner onto the motorway network as I still think that should come after the test has been passed, although I have taken plenty on it under the auspices of Pass+ and think it, on the whole, is a very good idea. Plus, although everyone is different, I've always been a bit concerned about giving a new driver too much to contend with in too short a space of time.
