I don't know why this other person is claiming that altering your driving based on what's happening on the road is a bad thing. Not adapting to the conditions is how many crashes happen in the first place.

All that other stuff in this thread about safer road design is really about removing the need to think about how to drive. So instead of making it so drivers need to give cyclists room, safe road design would just give them that room. But in the absence of those safer designs, people just need to drive more safely.
