I think it's smart to revverse park becsuse its easy to look whats up front vs whats in the back. Eg, if you are taking you car out of your garage and u happen to live in a busy neighborhood where there might be kids or pets then it's peobably easy to see from ur front window rather than turning ur head and look for such things. However with back up cameras now a days i dont think it should matter a lot. Probably habit from old times.
