I think the lesson here is, as stated above, practice a quick exit from your race car with all of your safety gear on. Practice going out the driver's window and the passenger window. Practice exitting the car with your eyes closed. Practice exitting the car with one hand.
Another lesson is that safety equipment needs attention and maintenance just like any other part on the race car.
