See the twin joysticks! One on the left doortrim.
In a aeroplane, joystick moves fore and aft , left and right, but all the forces on the pilot , G forces and gusts are up and down ( Z axis) so it does not much affect the ability to comfortably use the joystick.
In a car all the forces of acceleration, braking, turning, are in the same direction as the movement of the joystick, so the inertia of your arm pushes on the stick too, so the arm needs to be very well supported, and it will be tiring.
Also different people likely have different ideas of what is intuative.
Pull back to brake, like pulling reins of a horse, Whoa!, and push to accelerate,
Or is it pull to accelerate like throttle of a speedboat, or an aeroplane?
Also, as much as we might not notice, when cornering hard, or very hard, we naturally brace our upper body by holding two hands on the steering wheel, but with a joystick this is not possible, can only brace with spare hand if there is a good grab handle, so this is tiring and uncomfortabe.
More the 20 years ago there was an EU project on advanced vehicle systems and SAAB , (and it looks like Mercedes) got the bit on hand controls and built ( I think) the first joystick controlled cars, and it worked but the idea went nowhere, I think for all the reasons above, and a few more like sensitivity and driver coordination requirements. What happens when you sneeze? Or driver takes hand off to do something else as is common, Does the stick self-centre and slow down and steer straight, or just keep going as it was.?
Aircraft are stable and ok to take hands off for a few seconds if needed.
Would this car keeping going for a few seconds and then be programmed to slow down?
If a future car is intended to be autonomous 95% of the time with the driver occassionally taking manual control for short periods, then a joystick may be considered, but then how do All the drivers get good joystick skills so they are safe when it counts?
We’ll get more “ uncommanded” accelerations, and cars going off ferry ramps into the sea!
Pilots might love it however, but Grandparents and Great grandparents much less so.
But I’d love to try that SL out!
