It’s mostly a matter of where you drive. My last employer had a spread out campus, and my office was at one end of the sprawl. I usually walked, but sometimes I had to carry a lot of stuff, and I drove. Going through campus meant I had to pass a metal recycling business. There were screws, bolts, nails, and other metal scrap in the road outside their building. I had a lot of flats until I started driving around the industrial park, entering from the back. I didn’t have to get close to the recycler that way. Instead of less than a minute, it took about 5 minutes, but at least my tires were OK. I wasn’t the only one. The folks that worked down there always used the rear entrance.
