So, it is certainly a thing that exists. But when can it be used?
I drive a lightly modified 2016 Jetta 1.8t Sport. It clearly isn’t fully stock, but isn’t too extreme either. The Volkswagen enthusiast can pick up that it’s an enthusiast owned car, but your average 17 year old girl who drives a daddy’s money GTI probably wouldn’t.
In the five months I’ve owned the car, I’ve exchanged head nods with an Mk4 GTI and a Mk7 GTI and waved at a Golf R (He waved back.) But I honestly don’t really wave at anybody unless they initiate the wave.
I like waving at other VWs for some reason, it gives me a sense of approval. So should I start waving more? It’s kinda weird to wave at people and then have them look at me like I’m a loon.
