I feel sorry for the ground staff that have to operate these "modern" aerobridges that sit on the two manoeuvring tyres.
I've stood behind the staff on numerous occasions watching them operate the joy stick as they tentatively try and position the lumbering bridge to the front door of the aircraft. Seems to me there is only two setting for the electric motors that drive the tyres, ON and OFF. There seems to be no low gear option where the operator might be able to select a slower setting for the final approach to the front door.
I'm amazed collisions like this don't happen more often.
