i love mine ... so long as your in the right and don't take the piss why are you worried ?
always nice when they say why did it take that long to goto there etc... just tell em to check the tracker ...
if you disable em they call out an engineer to find out why its not registering, if this happens as a regular occurance your company usually get a nice big bill for call outs etc ..
so embrace the new technology ....
it can work for your benifit ... 60 mph on dual carriageways in a van is the max speed for a larger style van vito or dispatch etc....
all our lot have slowed down and yeah they loose jobs through it but saves shit loads on insurance so cant blame em really...
