Primary position

The one thing he disagreed with was how to manage an oncoming driver on a narrow street. I suggested that riders should hold their line forcing drivers to slow down and negotiate for space. He though that 'playing chicken' with drivers was not a good idea and that cyclists should always defer to drivers and pull in as early as possible.

To be fair, I'm sure he would give the same advice to a car driver in the equivalent scenario - a larger vehicle coming in the opposite direction. Avoiding potential conflicts is a cornerstone of the IAM philosophy.
