We have rules about elevators. There are elevator inspectors who regularly certify elevator safety, and they are liable if they falsely attest as to its good working order. The owner of the building is also responsible for maintaining their own elevator. There isn't anything the passenger of an elevator can do to meaningfully affect its operation or safety. I suppose if you knew there was someone working in the elevator shaft and you pushed the button to hurt them, you would be responsible for that.

We have rules about motor vehicle operation. The operator is responsible. If you are the passenger in the back seat of a cab, the driver is responsible, not the passenger. If there is nobody else and you are the pilot of an autonomous vehicle, you have to assume responsibility for your vehicle and its actions.
