What is it with Tesco Artic drivers, do they go to a special school on how to piss off other drivers or is it part of the induction policy. On my way back to the depot I had to overtake a Tesco lorry, as I get half way up the trailer the driver decides to slap on his indicator and immediately start to move into my lane. Had two options, keep the line and let him smack into me or move out to the middle lane. As luck would have it there was no traffic and the middle lane (3rd lane on M1 past Hemel Jct) so I moved over, as I went past the unit the driver was oblivious to anything he'd just done. Kept staring ahead and didn't even notice that I went past him.
