So, how long until the first lift collision, if cars are able to move
independently in the same shaft, one wonders?

But that "can't happen" because there's "A sophisticated computer program
and sensors [which] monitor the location of the cars and prevents cars still
in motion from crashing into cars that have stopped to accommodate
passengers."

Yeah, right. Would you trust it?
