No offense intended, but this scares me. They are ~everywhere~ for a long time around me. Quite a lot of driving instructors (specializing in 'reduced fuel consumption' trainings) use them as a general guideline to "see" how your behavior drives the consumption up. Heck, mum and dad use that thing for years and drive even slower since they first saw that they could make their car use less gas. You need to get a new car.. :)
