The biggest impact were cases where bike lanes were protected -- that is, the view of the road from the outside-in was pedestrian sidewalk, bike lane, car parking, and then lanes of traffic, so cyclists wouldn't have to worry about double-parked cars forcing them into traffic or inattentive drivers drifting into the bike lane. That said, such a change carries its own risks (cyclists need to be aware of passengers exiting cars and vice-versa), and generally requires more thoughtful design of the intersection (since cyclists turning left will have a much longer path to follow).
