It appears to me that NASCAR has been paid off...With the introduction of Toyota (a non american company)  there were immediate rule changes to make things (MORE COMPETITIVE), instead of allowing aerodynamics and body design a free run to develop as dragsters have developed and the inovation in safety and speed.

American and foreign cars are seperated by engine size and configuration of body and carburation and things like that competition is innovation and the willingness to dream. not making all cars the same so luck and fixes are easier to determine the WINNER.

Also WHAT IS NASCAR'S carbon footprint and yes they use gasoline and not other fuels like dragsters. NASCAR runs hundreds of miles and gets nowhere...I feel it is a waste of gasoline ,oxygen and the extra CO2.

I say shut down NASCAR and lets at least try to save the planet
