In some states its illegal to use a cell while driving. I personally VERY RARELY use my cell phone in the car. Its there, and if someone calls me and I think it's important enough I'll answer it for a minute and soon inform them "Well I'm driving so I'll talk to you when I get home". I am not confident enough to really use my phone much while driving. My mom does it CONSTANTLY though, all the time. She's never been in an accident except once when she was young a couple kids on a bike were playing chicken and flew into the side of her car. One of them died actually... very very sad. But anyway, she didn't have a cell phone then. So I mean, she's a good driver but she makes me nervous with her texting and talking all the time.
My BF was in a car accident once where a guy hit him at full speed while he was on his phone, smashed him into a telephone pole and crushed his car almost bent in half. Its actually a really dramatic story, because we were on our way to my house and I was driving my mom's car right behind him. I saw the whole thing, it happened so fast it was like a movie. It almost looked like his car exploded, only there was no fire. I was so scared. I parked my car right in the middle of the road and ran over to his car. He wasn't wearing his seatbelt, so his head smashed right into the passenger seat window and shattered it. I thought he was dead when I got to the car. Amazingly enough, he had been listening to a CD really loud and it was still playing so it was really dramatic when I ran up to his lifeless looking body. I was screaming and crying and pulling on the door and it wouldn't open (it was smashed shut) and I didn't know how to work his CD player so I just beat on it until it stopped playing. Then I ran around to the driver's side and opened the door and grabbed him by the shirt to try and pull him out but I couldn't really. I was crying and telling him to wake up and finally he opened his eyes and he looked so confused. He kept asking me "What happened?" and I would say "You got in an accident" and he would get upset and say "what about my car???" And I told him "It's ruined..." And he would start flipping out (because he was mad it was ruined). And then I would hold him and try to make him feel better while people bustled around us and the ambulance came and then he would look at me again as if seeing me for the first time and ask me the exact same questions right in a row again and reacted exactly the same every time. He did that probably 5 or 6 times before the ambulance took him. He had memory trouble like that for a few days, and he had a concussion and some major body pain but he otherwise had no real damage from the accident.
Still, it was really scary for me and I'll never forget it.
Basically what I'm saying is that I wouldn't have a problem with it if that kind of thing were outlawed where I live.
