The attitude shown by TCAS FAN is typical of the numptys who think that all thia H&S bull will keep them safe, the HI VIS is not a magic force field that wards of large trucks ! it is only as good as the guy driving the truck.
As I said in another post The very first time I put on a HI VIS I was very nearly killed by a van driver on an empty ramp.
Some seem to see these things as some sort of aviation status symbol, but all they are is a safety tool and just as I would not try to undo a screw with a hammer I dont see the need for the Hi VIS on a GA ramp on a normal day.
I regret to say that TACS FAN is one who as been drinking at the H&S font and like all who drink too much is not capable of applying logic.
