I've been commuting by bike for 6 months now and the biggest issue I've always come across is other drivers changing lanes and merging. I'm wondering if anyone else experiences these scenarios, and how they deal with them. --- When a car indicates to move into your lane, how much space do you give them? Do you bother to wave drivers through or give them a signal? I slow down to create a gap and maintain a distance of 9-10m or about 2 car lengths, but drivers seem hesitant to merge. It looks like more than enough room, but it might be a mirror/judgement problem on their behalf? I'm not stubborn, so if I notice they are still hesitant, I give them more space... but it seems very excessive. --- Second scenario, if a car attempts to merge into you, you emergency brake, they brake at the last moment. You both end up stopping. Do you let them go first, or do you pass them? I personally don't feel safe with them behind me, especially if they nearly smidsy'd me moments before. This happens a lot to me in the cbd even at reduced speeds. It usually creates a standoff, with cars beeping behind me and while I try to wave the merging car through.
