I don't understand being more lenient about DW-T/F than DWI, at least at a low BAC. It's comparably dangerous, and a lot harder to be mistaken. "Oops, I metabolize alcohol more slowly than I thought" vs. "Oops, I took my hands off the wheel, pulled out my phone...".
Yeah, you could argue me over to your position quite easily. My thinking is it's less dangerous because you can put it down. But I'd be fine with taking licenses away for DWT.
Hm, I guess that's a point. If you're intoxicated, you're intoxicated at the most dangerous bit of your drive. If you're playing with your phone, you might be picking relatively safe times to do so (at an extreme, I've been known to check things on my phone if traffic is literally stopped).
