They set off and meet up at the same places to stay overnight. I met a couple of guys in a car park last year and spoke to them for about 5 minutes, they'd been all over the UK and France, they were in a LHD car in the UK at the time. Basically they were agency workers who were getting paid what they thought was a fortune (about a tenner an hour) for simple driving jobs and they said it was far better than working in a factory/warehouse etc. They said the hardest bit of their job was changing the hard disk on the recorder every so often.
