In my observations, yes, some people do wear golf caps backwards, though it isn't common on the green. The traditional golf etiquette calls for hats to be worn forward, but outside the course, fashion often takes precedence. Many younger golfers and fans, influenced by the broader streetwear trend, have adopted this style. However, it's noteworthy that in competitions and more formal settings, golf caps are typically worn in the traditional manner. So, while you might see golf caps worn backwards, it's not exactly the norm in the sport.
