If you take a look through these pics you will find a JD CUT. I have to say this sounds real nice but the practicality of it and the cost has to be enourmous. Also what happens when the electronics fail have to be replaced? I guess the snow wont melt and you will have all kinds of accidents. There are too many other things to consider with this as well. maybe I am not just open minded enough! I personally think we ought to go to flying cars before we think about replacing all of our concrete and pavement with these types of things.
