I think this is an excellent product which gives an very good insight into what 'Advanced Driving' is all about. I passed the IAM test some years back, but found on watching the DVD that I had an incomplete undertanding of some aspects - which were very clearly explained, and also demonstrated, by the use of appropriate 'on the road' video clips (with some over-head shots from a Police helicopter).
I would recommend it to anyone thinking of doing the IAM or Rospa tests, to any potential ADI's or, indeed, to anyone who has an interest in better/safer driving.
What a pleasure to watch real experts at work!!
