I love the proximity warning part but would A- really appreciate being able to have it show feet as an alternative to meters & B- additionally it would be great to include green as a choice for all clear kind of a distance indicator. Having Red initially confused me. If I think in terms of traffic lights in the USA, Green means go, Yellow Caution and Red ( You better stop ) -this is what I had initially 'assumed' - but still the meter is great !
Since it was implemented, try using it!
