Short answer: no. ;-)
No, I am not daft, just trying to keep you interested. ;-) Read on for a
full explanation.

a few observations:
- forget about honda insight. it is not very fuel-efficient.
- the Prius can give you about the same gasoline consumption as a small
manual car (such as the alto, the i10, etc.). this is true both in-town
and out-of-town.
- one of the reasons that the Prius is much more

Hi Mord,
You are looking for something like this:community:
http://www.kml.co.il/Models/%D7%98%D7%95%D7%99%D7%95%D7%98%D7%94_%D7%A4%D7%A8%D7%99%D7%95%D7%A1
But you are right that hybrid cars have a lot of user-visible algorithms in
them, and I think this makes it interesting to reverse-engineer.
Hi
I know that this is off-topic, but I really don't know who to ask.
See, I need a large pool of Linux-like brains that live in Israel for this.
I mean, people (like me) who track gas liters and kilometerage, wear and
tear on the car, insurance and things like that.
Does anybody have numbers and
