Today’s invention is a rollercoaster with points -like a railway track.
This would add a certain extra challenge to those trying to hold onto their breakfasts, by allowing the car to take multiple alternative routes.
Rather than have these points change in a predictable way, it might be possible to have them switch, during the course of a ride, in response to the phone messages from observers and/or passengers.
The next step after that is multiple cars with the potential for overtaking!
