Let's be courteous not intentionally piss off the speed demons! Let them pass.
You definitely don't want to piss off another driver to the extent you end up in a dangerous / road rage situation. Better just to move away from them. You may have the opportunity to see them meeting the friendly CHP officer further down the road!
As a practical matter on CA highways, I travel the right lane when I'm going the speed limit or a touch below, particularly when I have the opportunity to follow a slower vehicle. You'll get speeders in the right lane, but it's the right lane and they can pass on the left.
If I'm going faster, I'll go in the lane that's flowing the speed I want to go.
If I'm in the left lane or the HOV lane, I'll go with the flow of traffic, unless the non-hov lanes are backed up, and I may go a little slower than the HOV lane traffic, but I'll change lanes and let faster cars pass me as they approach when it's safe to do so. If the other lanes are stalled, so I can't mover over to let faster cars pass, I'll increase speed 5 or 10 mph until I get to a place where I can let them pass.
Just as a matter of courtesy, supppose it was a two lane highway with turnouts instead of an HOV lane. If you have a pile of cars behind you and you're moving slower, would you take advantage of the next turn out to let them pass, even if it slows down a tiny bit? I would and do.
Sometimes I'm the person going fast (far left lane), sometimes I'm the person going slow (far right lane). It's a lot nicer to drive when people are being courteous and cooperating with other drivers. I know there are a lot of drivers who don't cooperate because they believe they own the road, are too busy with there cell phone conversation or never got a good driving education, whatever the reason, but I don't need to contribute to that, especially when that type of behavior becomes dangerous or even deadly.
I suspect we all have our own stereotypes for drivers of different of vehicles - BMW, Mercedes, Volvo, Winnebago, minivan, SUV, etc. Let's make sure that our actions as EV and LEAF drivers create the stereotypes in other driver's minds that we'd like.
