[aprssig] Prius Battery Life and Replacement Cost

sufficient heat when it is cold outside, but I do notice a considerably
longer time for the coolant temp gauge to come up to low end of normal.
Cooling, Its "okay" but I am a a/c tightwad it has to be really hot
before I will usually turn it on anyway, its no where near the cooling
power of a land barge but it makes it comfortable inside.  Remember that
I ride a m/c as much or more than 4 wheels so a/c isnt on my list of
super important items.

The insight only has a 1 liter engine so there is not a whole lot of
reserve power there, and it has quite a bit of glass area so it has a
lot of greenhouse effect when sitting in the sun.
