Yes to some degree. In comparison to talking on the cell phone, Yes! I hate talking on my phone while driving.
Hypermiling on the cell phone is suicide!
Following my typical 50-60 P&G on the highway with my eyes on the rearview, I would say I'm EXTREMELY AWARE.
P&Ging in the city or trying to be incorporate a new hypermiling technique then I'd be a little less aware.
