This is funny, my wife and I just had the conversation at dinner that it seems like the kids get much more car sick in the Tesla than any other car we’ve had. Then I searched on here and found this thread! We have 18” wheels. I think its just the overall ride dynamics, including the bumps, accel/decel, flatter cornering, and maybe the full glass roof. I feel like I’ve learned to drive pretty smooth, but we’ll have to try “boring mode” to see if it helps ....but I won’t be happy about it!
