I get your point but there is also a huge amount of aping what is successful. E.g., as gas mileage requirements increase, you'd expect things to become more aerodynamic. Separate from that, the Ford Escape was reworked to look like a knock off Subaru and the Ford Explorer was reworked to look like a knock off Range Rover. If it were just a matter of convergent evolution to fit the constraints of US gas mileage regulations, why did the Ford Explorer also copy the Range Rover's hood lettering?
