Using a phone reduces your reaction times as a driver in the same way, if not worse.
What kind of reaction time do you need when stationary, and what if you're too slow?
Oh gee, the drivers behind might get pissed off. Sticklers can get in the fucking sea. Rules have reasons, and it's the reasons which matter, not the fucking rules themselves. Carrying on like the above has any relevance when the dude is stationary is little more than an excuse to perpetuate tribal animosity between cyclists and motorists.
