Hi Mary. I thank you for your rational & informative posts and tend to agree with all that I understand. I don't believe there is such a thing as years head start with an app. A lot of the heavy lifting is already done. i.e. Tying into GPS and cars systems. I suspect it is the variable systems in different cars that is a challenge for the programmers to come up with one app. It could be a problem if different apps are needed for different makes of cars and different model years. And, it could prove very difficult to build for older cars - which "kids" tend to drive as their first car - which tend to have less "electronics". The many different phones on the market and coming soon could be an issue, too. I'm just not sure why the car makers just don't do it themselves. Thanks again. Go ONCI
