I disagree overall, but then again I'm not an extreme hypermiler either on the interstate, or in the city. In fact, I drive like a bat of hell in the city and am usually leaving everyone in the dust, as silly as that sounds. Most people accelerate quite slow. It is fun when someone wants to beat me though, it really puts you in your place and makes you realize how slow the Insight is.
It's others responsibility to be aware and pay attention. I should be able to drive however I want to drive, as long as it's safe for me and others. Driving slow is inherently safe, and driving even 20MPH under the speed limit is not and should not be dangerous, period. I pride myself on being extremely aware of my surroundings, and wish more people were the same.
I just laugh when someone flies up on my ***, sits there a bit, then swings around me all agitated when there has been plenty of room to pass the entire time. As if I'm going to go faster just because you're inches from my bumper. That's about the time that I tap my brake pedal.
The speed limit on the highways here is 75MPH, yet I rarely travel that fast. Maybe down the big hills.
It's never been a problem.
I am empathetic though. I don't like to be held up, so I don't hold other people up. If there is ample room to pass, like there is when I'm out on a road trip, I will continue driving the way I am, you can pass me. However, if we're on a twisty mountain highway, with no way to pass, I will speed it up and pull over the next chance I get. I've found that the Insight can carve corners faster than most people will go around them. I used to come through a couple of canyons in Northern California, taking all the turns at 50-60MPH. I easily stayed ahead of everyone, but it was flat and/or downhill.. uphill is another matter, lol.
