This is probably just an ‘unintended feature’, but it amused me so I decided to share.
To use this ‘feature’, simply activate Probability Travel, attach a jumper cable to a vehicle, step through an immediately adjacent wall, and attach it to another vehicle on the other side of the wall.
This will work for any 1-tile thick wall using a regular jumper cable, the heavy duty cable will work through much thicker walls of course.
It occurs to me that I probably shouldn’t be able to phase a jumper cable through a wall and have it function as normal.
Then again, what do I know about extradimensional physics anyways?
