Question for disc patients re driving (in the car)

Question for disc patients re driving (in the car) - do you use any cushions/devices/methods that helps you drive more comfortably?

I use a lumbar support and a “tush cush” as below:

and

I use something similar to the second item - i have one in every car i drive and on on my computer chairs - makes me sit correctly etc.

I found for me though the biggest issue for my back is not sitting in low car and the angle it puts my legs etc. I need to drive a higher car thats easier for me to get in and out of and more “chair” like in how i sit.
