Well where I live and the places I go VERIZON has done me good, I almost never drop calls and reception is about a 98/100% I would say... But this has nothing to do with what phone service I have...
Yeah I never get in my car and just "forget" about hypermiling or driving gently, but I still think that it could help, some more than others obviously...
btw, how much are vacuum gauges and how do you install them? Can I get one from like advanced auto or auto zone?
PSS: You say that vacuum gauges are cheap....well so are stickers
