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.
