I like how this software is able to show me where my fuel usage needs improving as well what are some other things that can be done in order for us get more miles per gallon out our vehicles! it has helped greatly over time because we have been using gasoline at an alarming rate (which was expensive). i think there should also possibly add another option about which type/size vehicle would need less gas than others? That's all so far but if anyone wants any questions please feel free too ask them here or email myself directly through their website :D.
