Didn't realise my car had this
The electro-hydraulic power steering has an additional feature: the "Driver Steering Recommendation" system. This uses software which senses when the car is going into a skid, and automatically corrects by giving the wheel a quick nudge. Recognising that most drivers find the idea of a car steering itself a little troubling, Seat is quick to stress that the robotic nudge is merely a 'suggestion', which the driver is free to override at any time.
