I used to ride one at the University of Leeds in the 1980s. It served a five floor lecture theater known for its brutalist 1960s architecture [1]. I rode it over the top on several occasions - the car went up one side, slid horizontally and then came down again. It was a good way to queue jump but allegedly could cause the whole system to jam, in which case the people caught in the middle would be carpeted. It's now been decommissioned, apparently.
