Review your footage! You're sat in the middle lane and never move from it, even when there was room in the near side lane after passing the dark people carrier! You are the problem and you are the reason people undertake and I'd have done exactly the same to you. People like you are a menace to others on the road as you're inconsiderate and oblivious to other traffic around you. Then you have the nerve to complain about other drivers who you've been holding up!
Wake up, look around you and move out of the middle lane. It's not a lane to cruise in. Dick.......
The car driver had right of way, so why should he allow a truck to bully his way through? People really are full of shite nowadays. If a car did this to a truck, they'd get a driving ban.
Where did impatient fit your description? You were obstinate and driving with neither care nor consideration for other road users Inc those behind the lorry forced to slow or move to lane 3 because you are petty.
You were going too fast, getting too close, and not driving in accordance with the conditions or hazards.
