Surprised that safety wasn't a statistically significant reason. Pushing your cart to a return exposes one to more parking lot traffic as a vulnerable pedestrian -- particularly worrisome for the elderly. It minimizes risk to leave the cart near your vehicle. Perhaps I have a really solid rationalization at work here :D

The amount of car traffic you are exposed as a pedestrian is way larger, that the few minutes in a parking lot are a rounding error. Also on a parking lot, there are a lot of pedestrians, so car drivers will drive even more carefully then on any random street, where pedestrians can also walk around at any time.
Wouldn't make too much sense because cart kiosks are typically no more than 4-5 parking spaces over. The marginal risk compared to getting to your care are basically nil.
