I generally give a wave, the missus and kids think its amusing. I've also been guilty of a non-return in defence either not seeing the other truck and/or my eyes aren't what they used to be if I'm focusing on driving. Also its bit awkward around town sometimes with the flash murraries maybe up themselves probably noone on here. The wave's a good thing to keep going its much more reliable out in the country maybe people are more relaxed there
