Spent a little time trying out the FAS technique over the weekend and on this
Mornings commute to work.

This Morning I tried it 5 times over my first 10 miles of driving,
2 times on flat and 3 times on a downhill segment. It felt to me that speed decreased too rapidly and didn't produce any better results than my normal driving techniques.

A real annoyance is if you have the NAV, everytime you do this it reboots. Also you have
to keep an eye on your SOC, because my short weekend test I also experianced a
forced regen for the first time (4 bars).

Perhaps someone who has performed this on the HCHI should try this out on an HCHII and make a comparison. For myself I am pretty sure I can do better without
the FAS.
