I would feel much worse if I was not putting too many miles in my Prius... already has 15K on it! This way I can at least justify it financially...
Which is possible, requires a lot of thinking, but it is doable....
The person who I was responding to implied that he/she uses the manual heater set on low heat... I'm pretty sure ECO has no impact on the manual...
Why not great things about a stupid car?
You are comparing the interior of your Prius with pretty good cars... in my case, I have driven pretty nasty cars so far, including an old 82...
Good numbers but you are getting no more than I would expect in such high temperatures (yes, where I drive, your temps are almost spring like for...
ECO mode is useless if you’re driving in the hwy and may help a little with city driving if you don’t know how it works. The only time it...

I know and I agree but the few times (maybe 3 or 4 attempts) I tried to measure wind, it was a mess. Every 80 miles or so I would check the wind...
