Your thread was actually quite inspirational for me, in picking this car. I'm still in awe that you're able to squeeze 50mpg out of yours, when most drivers are struggling to break 30 in an NA, even driving conservatively.
I've been a bit reluctant about EOC, even if it seems like very low hanging fruit, what with how the roads are here. The push-to-start probably isn't as scary as it seems to tinker with, but I imagine some of the traditional methods of killing an engine while driving might not play as nicely with the electronics.
My biggest economy hurdle right now is in my desire to take curves
very fast, which often means use of brakes somewhere down the line. There isn't a whole lot of weight savings to be found, so I'm kinda waiting to see how the nut behind the wheel adjusts.
