Interesting that you get downvoted for this comment. I cannot see why. Getting run over by a careless driver (and yes, looking at phone is a specific problem) definitely is a risk, at least in some places.

Where I live, I have dedicated bike/pedestrian paths so it's only a few intersections where I need to watch out. (a bit over 10 km, 25 min in the summer and 25-40 in the winter, plus the time it takes to shower and change clothes at both ends).
