Honestly, those that are disabled end up waiting longer for this attraction than anyone else. They also can only load so many doom buggies at once of the disabled because the transfer vehicles are spaced apart in the ride and for good reasons, it helps make evacuation easier if necessary.I think more people are faking the handicap to ride faster. Regardless what they need to do is wait until they have enough handicap to fill several doom buggies at once and stop less often! This would also help the handicap that requires more time. It does really throw off the mood when it stops and a cast member announces the stop.
years ago I had a camcorder with IR lights they stopped the ride and came to tell me to turn the light off. The cast member was a bit embarrassed when I explained its IR and they apologized. I bet I would never get a apology these days!
