Trying to understand on why phones are so dangerous combined with driving, now killing more people each year than drunks behind the wheel, research's been done showing people can't really multitask, only switch tasks rapidly. We end up doing a half assed job on everything, including being present for other people whether other drives whose life depends on you being sober and focused but also friends and relatives. I've seen countless parents focused on their phones not paying attention to their kids, which is really sad.
It's craziness as people could be much more productive if they did one thing at a time. That said, people who have the television running all the time probably aren't seeking to optimize their productivity.
