I’m surprised that you’re not including walking while talking on mobile too, as if it doesn’t matter much.

One can understand that texting actually keeps one’s attention on screen while walking when it is badly needed for surroundings. People nurture a false belief that they can be attentive to surroundings while talking despite mounting evidence to the contrary! Most of us are under the spell that we do far better than any normal man does in circumstances and nothing bad can happen to us despite our negligence/ misdeeds!

I’m in India, and know that many people here die/are seriously injured by crossing roads/railway tracks while talking over their mobiles. I’m pretty sure that it can not be different elsewhere!
