Normal Operation
Pull is a tugging sensation, felt by the hands on the steering wheel, that must be overcome to keep the vehicle going straight. Drift describes what a vehicle with this condition does with hands off the steering wheel. A vehicle-related drift/pull, on a flat road, will cause a consistent deviation from the straight-ahead path and require constant steering input in the opposite direction to counteract the effect. Drift/pull may be induced by conditions external to the vehicle (wind, road camber).
