Go to Post Code doesn't break. It reacts exactly the same time every time. When something new happens that never happened before, it's because the mechanicals, electricals or drivers gave the code some new stimulus that wasn't tested before. - GaryVoshol [more]

On the moment of contact, the front wheels hit with the axle at the top level of the bump. They won't roll up and over without help--their force at that point will be entirely vertical once they leave the ground, but without something to push them horizontally, they'll fall back down. The back wheels are what provide the horizontal force to get the wheel up on top of the bump.
