Overloaded taxi (3 passengers up front with driver) - cut me off on
the m1 just before the buccleuch off ramp. i tried to go around in
the emergency lane & he pulled in front of me coming to a complete
stop. i tried to get back onto the highway he did the same causing
obstruction to me and traffic in the left lane on the highway. he
proceeded to drive next to me on the n1 giving me the 'bird'
