That's because their nose is stuck in their phone. They don't see you, they are looking at the IPhone.
The Facebook posting of what Kimmy is having for lunch is way more important than your car!!
Our last trip through Sams club was a real treat. Stupid phone blind idiot walked right in front of me and I hit him with the cart. He got pissed and raised his voice. I mentioned I am pushing a very heavy cart and when I saw him step blindly in front of me there was no way I could stop. He started into pedestrian idiocy and I countered with I am about to stuff your dumb A$$ in the freezer so step off. He wandered off mumbling with his face in that stupid phone. My wife thanked me for taking the time to warn him of my intentions instead of just doing it as I would have not so long ago. People are not getting any brighter with the march of technology. I seriously feel the light between their ears grows dimmer.
