Certainly 4 hours of being told things that were true decades ago, but haven't been true since then. Things like car stopping distances, casualty rates for collisions at given speeds. Woefully pessimistic statistics based on the assumption that you're all driving cars built in the 1960s.
I don't see the point in bothering with these courses now that many insurers ask you specifically if you've ever attended one, which totally defeats the object of going.
I'm amazed insurers are allowed to ask given the intention behind them as to offer people a way out in return for education.
