I had them on my customised L200 pickup truck. I never wanted to step on them as they were highly polished stainless steel aftermarket jobbies. They were great for collecting all manner of detritus despite having mudflaps but at least there was always one part that was clean as I was continually wiping them with my trouser leg as I stepped over. I had to throw out all my pencil skirts as they were just too restrictive for climbing in or out.
On the plus side I never got any door damage in car parks.
