To be honest, this was kind of shown on the Stobart show the other night.
The planner went out with a standard sat-nav and it tried to take him down a road with a low bridge. Thankfully common sense prevailed with that but I think it illustrates the problem and why these problems occur
But he didn't know how to tie a load, do his curtains properly, or even about automatic trailer brakes (when main air resevoir drops), how did he pass his CPC?
And he was completely baffled by a telephone ringing in his cab the other week...... oh how i f**king cried laughing.
With all due respect, this driver appears to have damaged his trailer by failing to visually understand that he could not advance alomg the route ahead of him. What does this have to do with Satnav or any other guidance.
