Your analysis makes sense, if and only if the relative risk is compared minute-by-minute to get the factor of 23. I looked but can't find out if that is indeed the comparison. It could be that an hour of driving, during which texting takes place, is 23 times as risky as an hour of driving during which texting does NOT take place. But like I said, I don't know. This is yet another example of the shitty nature of science reporting.
