As long as they see me I don't worry. They might do stupid stuff like honk at me or pass with small distance, but it's unlikely they'll kill me.

The thing I'm afraid of is a car hitting me at high speed cause they didn't see me, that would probably kill me.

Is the data you're talking about the data from Ian Walker's study in Bath, England? The sample size was one rider - himself. Other folks have analyzed his raw data and disputed the statistical power of the effect described. That rebuttal has also been re-rebutted. So that's three published studies about this, and three sets of headlines, but as far as I can tell, there's only ever been one actual study that collected data, and it was based on one dude in one area of one country.

There's an easy fix for that; drive in the middle of the lane. At least where I live it's impossible to legally overtake a cyclist without switching lanes so for anyone driving correctly it doesn't make a difference anyway. Of course that's not a hard rule for every situation, but after a couple situations that almost killed me I just try to reduce risks. Car drivers hate us either way.
