The tendency of a car to turn left (right in RHD cars) when being driven by a
fatty. The driver's extreme weight causes the left side suspension to sag, making the car naturally turn left.
Although this can be a benefit if you normally make left turns, right hand turns will be negatively affected by the weight imbalance.
This effect is similar to
torque steer, a similar effect found in FWD cars and caused by driveshaft differences.
Unlike torque steer,
pork steer can be found in cars of any engine/drivewheel layout, as long as the driver is a
pork enthusiast.
