Lack of predictability can be a feature, at least according to Hans Monderman, famous Dutch traffic engineer. He believed drivers become more alert and cautious when there’s more uncertainty on the road. [1]

From my experience, segregating biking lanes, and having more than one so as to allow passing is a definite plus. Bike collisions can be scary, but it's cars I'm really afraid of.

FWIW, I cycle all the time, often in Paris, Montreal and Barcelona and have strong preferences for doing so in that particular order.
