A limitation of this interface is that it only approximates
the target orientation of the wheel for a given curve, but
doesn’t try to correct for the actual position of the vehicle on the road. If the driver steers too early or too late or doesn’t hold the wheel exactly at T, the car’s position will follow the shape of the curve, but not follow the lane’s median as it will deviate. Small lane deviations may be acceptable when the driver is only temporarily blinded and the driver can correct their position on the road when visibility returns. For letting a blind person steer a vehicle, small deviations will accumulate and rapidly grow unbounded, with the car eventually leaving the track. A self-correction mechanism could help a blind driver steer the car back to the median of the track after a deviation occurs due to steering through a curve. In theory, this may allow a blind driver to safely steer a car around the track.
