I live in Seattle and while i don’t know FL drivers I can say Seattle drivers are not nice. All credit for waves received goes to your Rivian.I started waving to other Rivians as soon as I got mine in FL, but I think in all that time, I got only one that waved back.
We moved from FL to Seattle recently, where there are a lot more Rivians, and now I get lots of wave backs. My wife thinks the drivers here are just friendlier than in FL. Whatever it is, I'm getting a lot more waves. I'll keep waving - love this truck and the fun and interesting people who drive them!
