Alright. The product seems pretty good, especially the marketing and the spin. But I would have to place it in the category of "cool gadgets that you don't really need". For $20-30, this might be a cool thing to try. But I am not going to shell out $70 for a little tool that will tell me how efficient I am or where I parked my car. People have been parking cars without GPS systems for years just fine. And oh, want to help me be more efficient on the road? I think that people who are serious about saving money already know to now accelerate fast, drive over 65, etc.
