I've done a speed awareness course - same reason. I found it interesting and valuable - I'd recommend it ;)

My employer was taken over in the '90s by an American company who wanted an IT business. They required everyone who had a company car to attend a safer-driving course - which was both classroom and on the road. How to spot hazards, where to position the car to avoid others' blind spots - that sort of thing. I still consciously use some of that.
