So, hopefully you guys can help me make sense of how the Insight operates a bit better. I went to a lunch meeting today and the trip is about 2/3rd 55 mph highway travel, rolling hills, bread and butter Insight wonderland. I was able to maintain 75-100 mpg nearly the entire 2/3rds of the way there. The other 1/3rd is 35-45 mph country roads with stop signs all over the place. Great when up to cruising speed, but the dumb signs you gotta stop for every time. This gave me a lot of tries at tweaking my regen braking technique. However, regen doesn't seem to be consistent. Every once in a while it just will not regen. My technique is pretty consistent though. When approaching the sign I shift to neutral and when I get closer to the sign I shift back into gear (usually 3rd) to get regen. Most of the time when I let the clutch out I get the 4 bars of regen right away, and then more once I lightly touch the brakes. However, sometimes I get no regen when I let the clutch out. Sometimes after that I get regen when I brake, and sometimes I don't get regen when I brake. Its confusing.

Also, since I was doing a good amount of regen, for a short time, my battery SOC meter went to 100% full from about half. Continuing driving, it later dropped down to about half full which is where it seems to stay. Is this normal?

I realize a clutch switch and other mods will help me control the IMA system, but I would like to understand better how it operates to begin with in stock form.

Still absolutely loving this car even with its not fully smooth lean burn (yet)!
