Why don't you get car sick in a bus?
Why don't you get car sick in a bus? Your peripheral vision will register the movement and create a contradiction in the brain. That's where the bus sickness begins. There are cases when people experience the dreadful symptoms of motion sickness only while reading while in a moving vehicle.
Is top or bottom of bus better for motion sickness?
Stay away from the back of the bus on the bottom deck and from anyone with a takeaway. Priority seats on the bottom deck are best. Second best is the top deck, three rows from the front, on the aisle seat.
