Honestly, no. I would never make that kind of mistake for many reasons. For a start, if I’m unsure of where I’m going, I will be driving much more cautiously because I know my attention is divided. So I wouldn’t be overtaking like that, not knowing if I was about to turn left. Secondly, I would be very aware of the vulnerable road user on my inside. If I had made the mistake of overtaking them then realising I needed to turn, I would not make that their problem and take the chance with their life that it was probably okay. I would swallow my pride, allow them back past and then turn behind them. To be driving in this way in the first place implies such a callous disregard for others safety that I think they should have their taxi licence revoked.
