I get upset when I have to change speed for ANY reason not of my choosing (other than DWL on hills). Any slowing gets me cranky, as it means using more fuel to get back up to speed- usually at an inopportune time. I mean, I'm already at/below the speed limit!

Since I'm in the right lane anyway I get hit with a lot of the merging traffic that may/may not care about where the merge lane specifically starts. This leads me to hang on as long as I can, hoping THEY adjust THEIR speed in time, in a twist on playing chicken in parallel instead of at each other.

I hate this, yet I persist. Feeble human that I am.
