I'm new here and I'm sure this has been discussed before. I do most of my errands by bike and am constantly amazed by all the idiots who feel compelled to check their messages and even send messages while walking, biking, and driving.
Here in the Netherlands there is no specific law against this sort of behavior for bicyclists as far as I know, though it is of course prohibited for the driver in a moving car.
I really get tired of this behavior. I know if I say something to the individuals who do this I'll come across as an old fart. I really wish the police would start giving out warnings for this behavior.
I know I'm not alone with this.
