I used to get really bad motion sickness as a child, which ultimately resulted in a strong phobia of coaches (the buses, not the Alex Fergussons, although he is pretty scary sometimes).
Why I DETEST those loud, heavy, musty, dirty people-carrying beasts?
1. Theyre loud.
2. Theyre heavy.
3. Theyre musty.
4. Theyre dirty.
5. Those massive wheels (scary).
