what do you do when you see another box?

[kk2002s]

When I was a teenager many, many years ago, I drove my fathers 914 from time to time. It was very common that a Porsche acknowledged another Porsche (even if it was 914). So now 35 years later I'm back in my own Porsche and I don't see this acknowledgement happening at all. I've only been at this for a month now and I have seen very few Boxsters. I can see the SUV and sedans not caring but at least a 911, Cayman show give a flash, a wave something. What are others around the country seeing these days
