Texting is too specific, it's smartphones in general...
I don't use my phone when I'm walking.
This is unfortunately very true, even for societies which are much more sensitive to this issue. As a regular cyclist in my hometown of Berlin/Germany I sometimes see so much as every third car driver looking at or obviously typing on their phone although this is illegal and of course dangerous.
I generalize but infrastrucures changes everything to a point where a city can easily get rid off car (give us a few years...). It's all infra since that's the only thing that changed here in the past decade: we finally dare to bike now, only because it's protected enough we don'fear for our life every few meters nowadays. For this reason, biking has become the default for most of my friends and colleagues. And the last few who haven't swichted are either taking the metro/RER or walking. The last drivers are professionals (who need to move heavy things and the infra does not support electric cargo bikes yet), old and fuck-you-momey rich boomers who still see biking as being weak, some families (who can afford to still live in Paris?!) but same issue as cargo bikes, and lost tourists (why the hell do huuuge tourist buses are allowed in so dense blocks?!).
I haven’t heard of any of them being put in place for actual enforcement yet though.
Second, I support any legislation to penalize texting and driving with penalties similar to or beyond what drunk driving currently gets. I am happy to support a criminal penalty of second-degree murder (i.e. ~25 years in prison) for impaired driving leading to death.
What more can I do? I'm happy to.
