Gatorskins, as mentioned below are fantastic for most things, but in my experience they are not fully resistant to the damage you mention.

I've seen similar bike patching mechanics on sidewalk stations in Beijing, and I feel like they would have a similar primary customer. The degree of construction and infrastructure work there means that there are always metal bits in the road. Nails, roofing scraps, welding rod ends, filler wire trimmings that get washed off construction sites in the rain and blown to the roadside by traffic are highly effective at puncturing bicycle commuters' tires. But they also make small holes that are a quick fix. Soapy water will show where the leak is, and pliers, a donor tube, and vulcanizing compound and you're in business again.

Gatorskins are harder, less supple, so they don't pick up the smaller bits of glass and metal that will work in over time. They are resistant to pinch flats by having thicker, stiffer sidewalls, so the bigger bits of metal or rock aren't so scary ( they won't be any more fun, you will feel them more ). But a nail is a nail and if you hit it head on it will go in.
