Toe -
I had to re-read your post a couple of times, because at first it came across that cell phones weren't a problem and that driving after some drinks was fine. It's so easy to read between the lines and be wrong in what you said. For the most part I'm going to support you here, though.
I doubt that vehicle collision rates went up noticeably per capita since the advent of the cell phone. ... I've been cleaning up after collisions for 25 years, and it seems to me that major vehicular crashes are actually down from the time before mobile phones came along, at least in the area I cover. I attribute the decline to fewer drunk-driving incidents, for whatever reason.
Drinking was socially acceptable when you and I were learning to drive and I remember sitting on the big smooth bench seat while my Dad drove with a can of beer in his hand. The numbers are clear that the drunk driving is way down and the overall decrease in rates roughly matches. Seatbelts? Heck our first cars had none, and then just those lap-belts that would break your neck. So, you're right about the overall rates coming down. The other biggie is that NHTSA has some good data to show that the roads and cars are a lot easier to use and safer by allowing more margin for error. A person may still run out of their lane due to drinking or a cellphone, but is more likely to have a wider median, grooved pavement, or other ass-saving technology save their bacon.
But if looking at what's going on now, the data is pretty conclusive that cell phones are consistently over-represented in the current accidents. From the March 2008 American Motorcyclist Magazine that hit my postbox yesterday, 51% admit to using a cellphone while driving. Those phones didn't exist when we were learning to drive, but there is a lot of data to support them being a current problem. Example:

Distracted driving is distracted driving, in any form, and more risky than focused driving. ... I've followed numerous drivers as they've been having conversations with their passenger, and have been amazed at how much time they spent with their eyes off the road ahead.
I agree with you but think there's a twist that gets missed. Other distractions were always there, but people are increasingly think that multi-tasking is normal. The AMA article points out that 70% of drivers also eat, 39% tend to kids, 32% read, 18% put on makeup, and 10% do work-related tasks, including using a computer. As I wrote before about my commutes, I've seen a couple of guys get a BJ while driving and one playing a frickin' coronet.
As for skill level of the driver and the drinking references, yes some people multitask or can keep slightly better alchohol-impaired focus than other people, but there's plenty of data to show that personal abilities are just where that individual fits within the population tolerance band. Those same studies ultimately show what Jill pointed out, that the individual likely won't recognize his/her own limits until things are grossly evident. So you may be closer to one side of the band. But we knew that, right?
