Yes, it makes it more dangerous for everyone. A big problem is when intersections are daylighted (i.e. there are no parking buffers near the intersection to provide clear sight lines for safe turning), but then people park illegally in the no parking buffers anyway. Now you as a driver or cyclist are much more likely to hit, or be hit by, something unexpected in the intersection, because you can't see it coming nearly fast enough. As a cyclist, even greens are dangerous enough (from cars running reds or pedestrians jaywalking) that I slow way down when I come up to a green with poor visibility, because it's simply not safe to trust the green.
