I'm actually surprised the numbers aren't a lot higher.

The bike path I ride to work goes through the local university and is split into three parts: one for walking, and two cycling (one for each direction). They're clearly marked, and it gets enough traffic that most people make sure to use the correct lane.

Almost every day, though, I ride past at least one person walking in the cycling lanes, headphones on, eyes glued to their phone, not paying any attention whatsoever to where they're going. Worse still, I've seen cyclists on their phones, riding down the walk lane, or the wrong way in one of the cycle lanes.
