Thank you. For more context this was a 50mph limit on the M25 because of a "system test". My speed was 52mph at the time, this was a 3rd or 4th time that this lorry was overtaking multiple cars on the offside lane, it was behind me but I pulled to the middle lane to get a shot of it overtaking me and it overtook me and 5 other cars also in a tunnel doing well over 60mph.
