This is the moment a biker flew into a rage and drove one handed at 70mph so he could give the middle finger to a BMW driver who he spotted FACE-TIMING on the motorway.

Andrew, who is withholding his surname due to his own road rage, spotted the motorist’s dangerous antics on the M25, near London Colney, Herts, on February 14.

Angered by the ‘reckless’ behaviour, power crane driver Andrew began trying to get the driver’s attention in a bid to show him the error of his ways.

The footage shows the motorist driving along while holding up his tablet so he can facetime with his left hand, leaving just one hand on the wheel.

Meanwhile, 26-year-old Andrew angrily rides with his middle finger out to him while honking his horn – though the BMW driver remains oblivious for a whole minute.
