Nice and explanatory. It's kind of complicated. Three modes: city, rural and highway are enough. Combine them with muting for less than PSL-20kmph (30 for the 50PSL in city environment, 70 for the 90 PSL for rural roads and 100 for the 120/130 PSL of the highways) and that's adequate and simple for 99% of the users. Of course I'm using EU experience here and all of the above cover the main threats a EU driver will face 99% of the time. In US or AU conditions are different and the way police works is not similar to what Stinger faces in Europe.
