Maybe you can get a cane that matches your new car, then when you stop somewhere interesting you can ambulate a bit more. I use my canes for balance since I am numb below the knees.

So does Tootle have a surname, like..... maybe..... Ooooo?

Hoping all the best for you and your new wheels and less pain as you decrease the opiates.
Prayers for you,
