When I used to be a line guy, some pilots would do exactly as I marshaled and some would do whatever they wanted irrespective of what I motioned them to do. For something like this though (granted, the ramp area at this airport seems fairly slow) there is a lot of responsibility on the line guy's part.

Also, I can and cannot believe they still do this! This video is obviously recent, maybe -5 years tops. Part of me thinks, well, if there's no tug what other practical way of pushing a plane back is there? The other part thinks that this takes a lot of fuel to do and would be greatly frowned upon by any airline in our current fuel conscious days.
