Your mom is a funicular railway
There’s no such thing as too much funicular.
Aren’t only the subset of elevators employing a counterweight so? Ideally, it should be a second car!
I hate when I get on an elevator and have to wait 10 minutes for someone to get on the other car on the 10th floor before it will go anywhere.
Then the bastard gets off on the 8th floor, and I’m stuck again!
Isn’t part of the definition that 2 cars counter-balance each other?
Typically elevators use their own counterweight, not other cars, as that would be less flexible for traffic. Since the counterweight can fit in the same shaft space beside the elevator (the shaft is designed with a little extra room for the weight), this eliminates needing another elevator car.
Most places I’ve been in with elevators have only one car/shaft - only very tall buildings have multiple elevators beside each other.
