The only reason that escalators can’t curve is because the steps are square. Round ‘em off, and those curves can happen. Yes, please!
I guess the problem is that the handrails would either move at different speeds (depending on whether they were on the inside or the outside of the curves) but that could be solved by using segmented handrails that expand and contract …. or just by using smooth metal that doesn’t move.
Please install a spiral escalator somewhere! (NOT Dubai!)
