<human>: My father has always been an unsafe driver, I just saw it as normal before I started driving. He would drive my sister and I to school with a newspaper propped against his steering wheel, for instance. Surprisingly, he's been in no serious collisions, and that gives him a false sense of security. After I got my license I spent almost no time as a passenger in his car, but he's given me rides frequently for various reasons since I moved back to town a few months ago.

He is always looking at his phone. When I tell him to stop and focus on the road, he gets snappy with me and tells me that his driving is fine, he's been driving almost twice as long as I've been alive,  etc. I then continue to tell him that I don't care, put the phone down or I'm getting out of your car, and he will oblige me, but still pick up his phone briefly on a fairly empty road, or at a stop light, where he will then fail to notice the light turning green.

I have anxiety issues so I'm never sure if I'm worrying too much about things like this, but I don't want to get in any vehicle he's driving anymore. He will no doubt take that as an insult when it comes up. Moreover, I'm worried for his safety. He usually drives fairly well despite his shitty choices but I've seen him drift into the middle of the road a handful of times. He also never EVER uses his blinkers unless I get up his ass about it. He doesn't seem to respect the danger inherent in driving whatsoever. I'm worried one of these days he's not going to get lucky anymore.

Give me a shortened version of the text
<bot>: how can I talk to my dad about his unsafe driving habits without making him get defensive, and help him grasp the full seriousness of it?
