If this design does end up successfully meeting requirements for both road and air (regulatory, as well as utilitarian), it is entirely likely that it could become the more popular than C172.
I agree with you. Although, if you have a look at Carplane's design you'll see that it already meets the regulatory requirements for road and air travel. Rutan is extremely capable, but his initial concept vehicle is a long way behind players such as Terrafugia and Carplane right now. As a potential customer I'll be overjoyed if there are multiple options (competition tends to reduce prices!) but right now Carplane is running second only to Terrafugia in terms of maturity of the project and ability to execute.
