RE The Bus allows 2 people to work against each other
Cant help but wondering why both a feedback loop and some sort of vibrator on the sidearm controller when a discrepency re position/command is above a certain value say 5 percent. Thus even in a high noise environment, and with shtf, a tactile warning to " get your acts together " would be obvious and not dependant on visual or aural. ( above is a super simplified version- do not mean it is a minor tweak )
