Has anyone done a Mature Driving Course assessment with IAMs? See
https://www.iamroadsmart.com/courses-services/for-individuals/mature-driver-review/ I am considering do the course out of interest and so see if my driving skills perhaps need improvement in certain areas. I think it will be interesting for me as I have done done a IAMs test since doing the more stricter equivalent way back in the sixties.
I think its an excellent idea. Due to my previous training I get asked by quite a few people I know to "assess" their driving as they feel as you do. I have been more than a little concerned by just how bad, bordering on truly awful some of them have been

I think everyone should be regularly tested, say every 10 years until 70, and then every 3 prior to licence renewal.
On one occasion I had to scream BRAKE ! because the person I was assessing simply hadn't seen a car approaching from his right as he (started) to pull out of a side junction into its path (60mph road) It was VERY close. If I hadn't been there it would have been a very serious crash.
So I would implore everyone to have their driving assessed on a regular basis as many have had no assessment since passing their driving test 40 or 50 years ago!
Bad habits sneak up on you. I have a fellow ex traffic cop assess mine yearly, and me his. Seems our training was excellent as we each comment on how the other is still very good.
