Im sorry he tells you what you should do, Not a racist or anything but it sounds as if he has not been here that long as it was real hard to understand him at the best of times, LO08 UDX he delibretely cut you short too as he cut off your cycle lane, So both cabbies were to blame
Bit of a tough one this, over congested roads and everyone more important than the next guy. Unfortunately the cyclist will always come off worse so best just try to avoid drivers like this and not provoke them.
Hope you reported it to the police. If he does it again keep your doors locked and your hand on the car horn to raise attention. Drive to a well-lit area like garage and continue doing the same.
Really if i ever see that taxi. I WON'T get in.
