The article with the Darth Vader pic, on p20; that's me. To quote the blurb: "Another new series of articles track the trials and tribulations of a new member of the driving instructor fraternity. Following on from our series last year looking at the challenges and honest impressions of a learner driver, here we look at the trainee driving instructor, why this industry, what he expects, and what is actually delivered on the road to becoming an ADI." I hope it can help others considering this career.
Here's a very topical shower of advice. There is another page of help on this site, but the point is worth making again, and "there's more than one way to skin a cat" (as the English say). Not to be confused with "enough room to swing a cat". Yes, we are a nation of animal lovers, after all.
If you do need to park diagonal to the kerb, bear in mind your front overhangs more than your back. (That's the extent of the car beyond the front or rear axle).
Because most modern cars are designed to slope slightly forward, the front "spoiler" (the plastic part of the bodywork, beneath the bumper) will be closer to the kerb or grass that at the rear. As you can see, there's a real danger of bending or snapping that part. And, while they're designed to be springy, they can crack.
Replacements are expensive. So move forward carefully when parking face-in toward the kerb. Proceed very cautiously, just as when doing a turn-in-the-road (and for the same reason). You you then can hear, or feel, the car make contact with the grass verge, and stop before you do yourself costly damage !
