Issues Safety concerns – 2012 results Safety concerns with servicing carts on the opposite side of the cab and not in direct line of sight, relying on camera system and mirrors most of the time. Two property damage incidents in first 30 days. No damage or safety issues in last 5 months Shadowing on video screen limits visibility. Camera angle adjusted & improved visibility The mental awareness required to service both sides of the alley (activating joystick switch, observing both sides of alley and cart location) fatigue could lead to missed carts and/or accidents.
