I'd say it's conditional. At a certain point, it's on the business themselves. For example, a giant parking lot with one or two cart returns only, in a front corner.
A massive sprawling Walmart parking lot with only one return, and I had to park really far away, and it's super busy and trying to get the cart to the return requires going through multiple rows? I'm a goodie two shoes who will clean up after others, and tries to improve places... but I've got limits with time, effort, and desire to deal with crowds of people in parking lots.
If they have good placement though, then yes, it's absolutely on the individual.
