Who said it sucks? I said the drive by wire was a pain. I would rather have a throttle cable going to a throttle body... not a computer that is trying to interpret my intentions and at the same time trying to get good gas mileage and protect the engine / transmission. locker might have helped as the slip function takes about 3 seconds to actually apply brake to the slipping tire. But still, the drive by wire will not let you power brake.
I still cant believe that a full sized Ford diesel crewcab with stock tires was doing better than I was...... oh the humiliation!
