It is nearly unbelievable to me that this hasn't been done already by shipping companies.
As for the UK, I have even less of an idea. Either way, this fella had to call in each time a haul was transferred, so it seems that he's saved himself and the company a bit of trouble.
The amount of data that you can get is pretty impressive from tracking a driver in real-time. There are even versions with cameras pointed at the driver and the road to record any "adverse events". In this way, it's less focused on the driver and more focused on fleet management.
I interviewed for a job in Las Vegas last year where I was shown this sort of technology for the trucking/shipping industry, albeit more server-based and not so distributed.
My hats off to this guy.
