If they're truly paranoid, they wouldn't be riding at all. How about: Ride as if all cars don't see you. That's what I do and I'm rarely surprised. I always assume that people waiting to turn don't see me, people merging don't see me, etc. I presume you meant visibility. I'm a big believer in that as well but I don't think a solid color neon works as well as something with contrasting stripes. Doesn't really matter what the colors are, as long as it's a stark contrast. And you shouldn't be pulling out in front of anyone in a manner that causes them to immediately react. If the driver behind you has to adjust because you've pulled out in front of them, then you just pulled a jerk move and didn't leave yourself enough space.
