It was the best thing o ever did, even though it was over 40degrees the day I did it. It taught me how to get out of trouble even in the wet. You learn how to control your car. It stopped me from t boning a girl and probably killing her when she pulled out in front of me last year, I hit the back of her car instead of her door. You learn how to brake safely without relying on the abs and traction control, where to look etc it becomes second nature.
