Have a model 3 with 20s on it (which does make ride more bumpy) and my 20 month old son has gotten car sick twice in the last 2 weeks. Never happened prior to now. My husband has always claimed the car makes him nauseous as well. Wondering if I should try setting regen to low. Don’t really want to spend the cash upgrading to a Y right now, but maybe I should consider that? Both times I made sure the back AC vents were on and it was a nice day today. Any thoughts? Hoping my heavier cybertruck with more tire will have a smoother ride.
