SAS,
Can you imagine the chaos?? Lol, it is an interesting subject though, the evolution of slinging/long-lining, things were just done because they had to be and people learned as they went.
Different times now though.
PS, can you imagine your senaro in a Left hand drive Astar with the door off and gauges bolted to the outside? Throw in a 5'10" tall driver, then it gets interesting!
