The other problem is that you are trying to count on the car buying public making rational intelligent decisions. Toyota's success is overwhelming proof that a large proportion of the car buying public is frightfully stupid.
It shows that many people are willing to pay a premium price for an basic appliance that delivers nothing extra to the ownership and driving experience.
I do believe that you should only pay limited attention to the competition and build your own product and make it the best possible. I certainly do not want anyone to emulate the Camry, no matter how many people are dumb enough to buy it.
