Maybe it's an age thing, but I always treated cars like they don't see me. One of 'em almost hits me? Then I wasn't paying enough attention, and didn't leave myself enough wiggle room. I've been cut off, and I've had my share of left-turn gravemakers ahead...and if there's one thing I know, it's that in no case has anybody ever purposefully tried to kill me. Poor drivers? Maybe. Could something really, really bad have happened to me? Yep. Did they do it on purpose? Nope. And that makes all the difference in the world. I got this thing on my bike, works off a switch on the handlebars. A short blast on the horn and a friendly wave usually gets their attention. If I get taken out, I get taken out. It's my time. I don't think it's here yet, and I ride like no one can see me...and I've never gone down in 30 years. It's just my way--I'm not a vengeful guy.
