It's like that every day for me. +10 on the bright clothing. +10 on the advice to OWN the lane. I'd rather they honk knowing I'm there than to take me out with the mirror. But that said, it used to be 30,000+ people dying on the roads due to driving under the influence in the US each year. Death toll makes it seem safer to my bro-in-law who was serving in Afghanistan... comparatively. But while drunk driving has been slowly going down over the decade, the number of deaths are rising due to distracted driving with texting. Here in CA, we have no texting while driving laws, but lack of enforcement, and just plain driver negligence has at least 10% of the folks texting in the car. It causes all sorts of other issues. E.g. people who delay others behind them at stop lights because they aren't aware the light has turned green (which can get drivers irate who then punch it and speed through on reds or yellows and ignore cyclists already in the intersection). Another issue is the drifting that causes encroachment of drivers into the bike lane. And yet another issue is that they create long slugs of cars tightely spaced behind them who are irate and want to pass. This bunches a long string of cars behind the slow driver who's texting. And that creates a barrier for cyclists would are looking to change lanes to the left who are trying to pedal hard and insert into traffic but can't. All this must add up to more cyclists at higher risk.
