How to tell driving instructor you want to quit?

It is well known that students have different learning styles. But, only very rarely do teachers have different teaching styles or demonstrate the ability to adapt to the learning styles of different students. In fact, most teachers adopt the so-called, "my way or the highway" approach to teaching (no pun intended). It is your responsibility to take control of your learning - if you aren't getting what you need from an instructor then find someone more suitable. It's your money (or your parents) so demand value for money.

At the end of the day, you don't learn to drive by being told how to do it. If an instructor can get you to pay for 90 minutes whilst only delivering 40 minutes of actual hands on tuition, you are going to need more lessons which means he is quids in! I suggest you call up a range of instructors and ask them what they think is a reasonable split of verbal instruction to hands on tuition, then get them to stick to it.

Just be straight with your current teacher, "I'm not happy with your performance so far. I've looked on the open market at the alternatives available. I'm going with instructor Smith because he's promised to deliver x, y & z." This makes it hard for him to throw the usual taunt at you: "you won't get better elsewhere you know!" Understand that if he then promises to change his lessons to suit you, he is merely confirming that his strategy up to that point was to extract as much money out of you as he can and he doesn't want to see his little cash cow walk out of the door.
