To avoid swaying, choose a seat close to the centre of gravity of the bus, midway between the front and back wheels. As the bus turns a corner, this point will travel in a smooth circle. That’s better than the front or back, where you travel in a narrow ellipse that lurches round the bend at the start or end of the turn.
2. Maximise the View
Looking straight ahead at the road is important to help your brain anticipate the movement of the bus and to keep the signals from your eyes and your inner ear synced up. The front seats on the top deck or an aisle seat on the left-hand side of the bottom deck are best for this.
3. Minimise Smells
Your sense of smell is heightened when you are nauseous, which will make engine fumes and food smells even worse. 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.
