Not so far off, except that this was a long, straight, narrow road. Mill Road, for those who know Cambridge. So even if you pass a bike there it won't do you any good, you'll be stuck at the lights in a moment, or at a zebra crossing, or behind a delivery van or another set of lights, etc. No point at all.
The guy was too close behind, I was in primary, I was passing other bikes in sub-secondary (i.e. any closer to the kerb and their pedal would be scraping). I was going as fast as was appropriate for the conditions, any faster and the assorted pedestrians and cars coming out from side roads would have been too hard to judge. Guy behind in his car wanted past, for no gain.
