This year I have had 3 near misses in about 60 hours of flying, some as a passenger in a shared plane. Every time we fly we get close to other aircraft but two of these close calls were due to the other guy's stupidity. One where the guy got his circuit wrong and descended on the live side and flew straight at us over the downwind numbers. We reckoned he never saw us! The second was a Europa overtook us and came within 100 metres. He said he never saw us and came very close to an RV before completely messing up the circuit and upsetting a few folk at an LAA flyin. The third one was when a twin came very close while under a LARS..when I protested I was told he had seen me and flown behingd me.
I'm not saying my flying is perfect (I know its NOT) but it is incredibly busy at times. Avoiding VRPs and VORs has to be a good idea.
