They’re complaining about pedestrians not being vigilant. I’m saying drive slower and more carefully, fully expecting that peds will carelessly cross the road, and there will be fewer issues.
We agree that you did make up the "go-kart" nonsense.
On responsibility - each party has one. Don't stumble across streets glued to your phone; don't drive recklessly. There's no point pretending one is the real responsibility. It just adds noise.
This view was not espoused by the OP. You've made it up for some reason.
