It seems to be a Continental lorry, so there may perhaps have been an issue with which side to of the carriageway to drive on. Our right turn is their left turn, and perhaps the driver prepared to make a wide left turn before realising that wasn't too clever. That said, I have no idea why they would have wanted to drive down Loughborough Road.
Satnav will take them that way for anything near Coldharbour Lane as it's no left turn off Brixton High Street and some satnavs won't understand going around the church to make a right turn instead.
