From previous experience, in places like Pointe Noire (very congested at times) when in a tight situation I opened my window and stuck my head out, and if in doubt, got a wingman.
I was also at Harare once and a BA 747 called the tower and complained that if they hadn't had a wingman, they would have collided with a parked plane even though they were following the taxi line. I certainly don't trust taxi markings in the third world but one would expect them to provide clearance in developed countries.
