I think I am a marginally above-average driver, but only marginally. Which is why I am quite careful to drive sensibly and safely, although I am a little prone to driving too quickly sometimes. So far, I'd say I've done OK, with two minor prangs in 35 years of driving, one of which was someone reversing into me in a motorway service station
ETA: I think I'd want everyone on the road to at least think they were a
competent driver, otherwise what are they doing driving? Occasionally you'll hear someone saying "oh, I don't like turning right, so I go around the block", or "I can't reverse"...and I wonder what other skills they may be lacking that they
don't know they haven't got? Anticipating problems, or hazard perception, for example?
