trackless

Yet in 1941, the city’s last “antiquated” orange streetcar had been replaced with diesel buses and electric trackless trolleys.

Later on, I marveled at a fleet of Teslas moving on trackless platforms across the floor, almost beckoning me to get inside them like a ride at Disney World.

The Challenge of Mondor, an interactive dark ride, debuted in 2006, introducing a trackless vehicle system — a technology not often used at that time that is now more commonplace in the industry.

So, it’s no wonder that the idea of a trackless universe devoid of intelligent life fills us with the dread of cosmic solitary confinement.

Robotics, digital trickery, trackless rides — modern theme parks are full of technological innovations.
