There is a danger to drivers in becoming so cosseted by their vehicles’ support systems that they make mistakes.
Today’s invention is a driver’s seat which operates like those in cinemas which react to film content and give the occupant a small shake.
Everyone who had ever skidded on ice, even a little, knows that the effect is to get one’s attention very tightly focused on the job of driving.
The seat in question would therefore react to a period of no driver movement (sensed by measuring weight distribution on the seat panels) with a very small-amplitude simulated skid movement.
This would get a dozy driver to sit up and pay attention.
