If there is such a great risk doing that, do you not think that sharing the road with a car would be even riskier?
I.e. if there is no trust i can glance at a screen when i am on a cycling path with nobody around without injuring someone else, how can I be trusted while sharing the road with cars/buses/trams?
take the risk of asking for trouble while cycling on a cycling path with no other cyclists near me (within, say, 300m).
You don't know. If you start looking at your screen and you are moving, you are a danger to others. I don't care what happens to you, but I care that you don't hurt others. And you may.
