in the u.s. and i'm against it. i'm sorry, brake-by. they have tested it in europe and they use on it some vehicles, i do not in any way, shape, or form like it in the u.s. for a multitude of reasons. i don't think it should be used at all. hydraulic brakes do work as long as they are maintained, the harder you stand on them, the more brake pedal pressure you will get. however, if you fried to go to the all electronics, you will have problems. you have crash control and stability control so the computer is attached to everything. the average car is 20 little computers and modules and they need to be maintained and even if this is an '08, if there's a problem, it's electronic or electronic interference where you can't control yourself. >> i'm glad you cleared it up. i didn't understand why you can't manually deal with the throttle but can the brakes by dealing with that problem. forget my advice of rolling out
