Driving back to Kendal from Egremont in West Cumbria in awful weather conditions - torrential rain and flooded roads. I was following a Highway Maintenance Lorry, leaving plenty of space for improved road visibility due to the amount of vehicle water spray. Ford Kuga proceeded to tailgate me dangerously for 5 miles, overtook me on a flooded section of winding country road, cut in front of me behind said Lorry, achieving absolutely nothing and nearly causing a terrible crash.
