Unless you like going fast in a 25 to 45 mile an hour zone, forget a detector. Sell any hybrids you own and get your detector on a gas guzzler that likes 70 to 100 mph. All cars and my motorhome get lousy mpg after 60 mph. Yes 65 will not mess up too much. But even my porsche will get 37 mpg on a highway when less than 65 mph. I have owned the first insight, civic hybrid, new accord hybrid (and for 2 stupid years a Acura TLX v6) and now the Clarity for 10 months and 10k miles. I have used 11 gallons of gas so far (getting 7 next week). If you are not a person in a rush all the time you will love this car. But it will zip along when you need it. But if you like to race to redlights and stop signs (and forget to regen) then buy something else.Thanks! Never actually have seen the OBD power ports...kind of a great reversible idea. I've used the Add-a-Fuse circuits a few times over the years also but my favorite installs over the years were just tapping into the mirrors or dome lights. These were of course on higher volume cars that many people have done the same and knew the wire locations.
