My wife suffered a badly broken wrist a few months ago, which has left her with restricted movement and weakness in her left hand. This is causing difficulty in operating the handbrake and gears on her Mazda 6 estate car as well as using the steering wheel, to the extent that she does not feel confident enough to drive the vehicle. I believe an automatic with either a foot operated parking brake or electronic parking brake would restore her confidence together with a steering wheel handle spinner knob attachment to give greater control of the steering. Is the use of a Steering wheel knob legal and what vehicle would you recommend to replace the Mazda 6 estate? The estate car is needed to transport our dogs.
