Sure, but how many actually get caught? I was just in CA and they have similar rules, and I saw a room of people on their phones while driving. It’s just so commonplace that enforcement is an absolute joke.
So if enforcement isn’t working, the next best thing is to quarantine cars. Reduce the routes cars can take through cities, improve transit, and make more separate bike and pedestrian lanes. If people are going to do stupid stuff regardless, at least let them only impact other drivers, not the more vulnerable portion of the public that share the streets.
