@hankinjax - yes, it's motion sickness and I experienced it in the beginning. In an ICE car, when you see something ahead for which you need to slow down, you take your foot completely off the accelerator and the car just coasts. In your Tesla, when you take your foot completely off the go pedal, the regeneration kicks in and slows the car dramatically. This is the issue. You'll need to get good at using the pedal to moderate your speed and instead of completely letting off the pedal, just ease up on it a little and try to mimic the coasting of a gas car.
