Cedar Point's Top Thrill Dragster used to have a similar procedure, but I don't think they ever rechecked the train for somebody pulling down a bar, and that policy is gone now. Maybe SFMM could attach placards to the trains saying not to pull down the lap bars? Or, maybe next time it is down for maintenance, maybe a system could be installed that locks the lap bars up until a ride op comes around and pulls them down.

I take a stand against unnecessary neutering of rides.
