Travelling at the front of a double-decker is a fun experience. You always feel like you’re about to hit something as you lurch through crowded streets.
When I was young the buses had a mirrored tunnel between decks, where the driver could look and see what was happening upstairs. My sister and I used to push our tickets through a little hole into the tunnel, and were always terrified the driver would catch us. Nowadays there are no tickets, and the driver has CCTV.
