I really dislike travelling when I can’t see where I’m going.
Today’s invention addresses this issue for train customers.
The carriages run on a track which is deliberately curved. This would make journeys longer by a factor of Pi/2 and allow only slower moving trains, but the attraction of facing forward is not to be underestimated.
In addition, seats would automatically swivel so that passengers would always be facing forward (as they look ahead out the windows along lines like the red, dotted one shown).
