Not untypical behaviour from a private hire cabbie. Not keen on queuing, he overtakes on the wrong side of the road in to oncoming traffic. Having avoided a head-on collision he parks himself near the front of the line of traffic.
How much time did he save? Absolutely none as he prevented from turning right by more oncoming traffic. All the cars he initially overtook pass him. Pointless and dangerous move from somebody who drives other people around for a living.
Absolute best driver about, can get from A to B quick
