Put a Donald Trump sticker there instead and see what happens.
I don't wave at people, maybe in my small town, but I'm too busy driving and watching out for idiots behind the wheel and stupid pedestrians.
I don't know what it's like in US/Texas, but here in Canada it almost becomes a game. People don't even look when they step out on the cross walk.
Drivers are the same, they depend upon the other driver to see them while they coast through stop signs, red lights and generally don't pay attention.
I find driving one of the most exhausting things I have to do, so I don't have time to wave.
It's even worse now with all these stupid tourists on the road in these rental motor homes where they are not really comfortable driving them.
They have no judgment how big they are.
