Tailgating, erratic and intimidating prick.
Weaving in and out of traffic, flashing lights and trying to undertake. Clearly found the whole thing hilarious as they drove past.
M6 Northbound - roadworks near junction 14. Approx 22:00 3rd August. Elderly driver travelling in lane 2, crosses into lane 1 without checking blindspot I sounded horn and took avasive action, swerving into hard shoulder to avoid him. Other driver bewildered and his passenger completely oblivious. V poor lane discipline, kept switching lanes afterwards. Reported to Staffordshire police.
Lane hopping idiot, nearly hit us pulling out in front of us then cut into lane in front of a lorry
