I think a lot of people who've killed someone while talking on their phone thought they were still "good drivers"
However much someone thinks they're a good driver, I still don't think it's right and I still believe it's gonna effect your ability to drive safely
If someone I love was hit and seriously injured or killed and it turned out the driver had been on his phone, I'd probably want to smash his skull in. I just think it's selfish to do that - if it's just your life you're putting at risk then fine, but what if a little kid stepped out in front of you - do you honestly think that your concentration wouldn't be effected even in the slightest?
