 very easy to program in another line of code that says with navigation system sees as the speed limit sign number it's all through all of that collection of data and navigation it will then say okay the speed limit's 45 you can't go more than 55 but what if the speed limit changes it may not know and then you're driving way below the speed limit and every other car that isn't a new vehicle is going to have the ability to go as fast as it wants so this says to me
