Pilot car should have backup Radar/Lidar as well as the antenna to detect if no sufficient clearance. Likewise, there should be constant electronic Comms back to oversized load, with deadmans trigger + visual cue if the insufficient clearance height is hit. You can add the (almost certainly to be 100x less reliable) human in the chain if you want, but that should be in addition, not instead of. The Oversized truck should also have an electronic map, which captures cautions regarding height speed issues along every part of the trip. Simple technology, with a bit of process, could eliminate about 95% of these errors that likely exist today. Of course, that 5% will still bite from time to time.
