My HCH-II is "supposed" to be here in about 10 days. Any advice on the test drive? Things to try, things to look for, etc.

All of the negotiation is complete - I just want to have a thorough "hybridized" test drive.

I've never driven a hybrid before, but I've been practicing my "hypermiling techniques on my car for about 10 months. I get 28 to 29 mpg overall on every tank on a car rated 21 city /28 hwy.

Thanks.
