I've said it multiple times on here and I'll say it again : Stores nationwide should institute a policy that motorized carts are kept corralled and out  of customer's reach, to be doled out by store workers-and only doled out on presentation of  adoctor's note stating the cart is necessary. Staff would be allowed to distribute carts at their discretion if there's no note, when the customer is obviously disabled (eg a cast on his leg). This would not 100% end the abuse of motorized carts-too many employees are themselves fatasses, and they will happily give them out without notes to fellow fats, at least till reprimanded-but it would be a good first step.
