Gonna try to have something up within next couple'a days.
But in the meantime... it seems to me that a momentary hard press-and-release of car brakes right before a speed-bump, with the right pump-measurement and at the exactly right time, will allow a car to gracefully swoop over the speed-bump at any speed and not feel a thing, as if it wasn't there at all. Maybe a vehicle has a velocity at which it will fall apart while doing so, but until then, the maneuver seems like anti-resistance that thoroughly erases the value and presence of the cement-mound. Course, not all speed-bumps are made equal.
Something to do with centrifugal force? I wouldn't know.
