A 29 year old man was charged with dangerous driving today by @PSNIABC after allegedly driving at 150 MPH on the M1 whilst filming himself and later posting it on social media. The offence allegedly occurred last year. This is one of the highest speeding detections Iâve known.— Jon Burrows (@PSNICIJBurrows) April 30, 2018
