I would mention that comparing a racing game to a first person shooter is pretty ridiculous. How many physics calculations are devoted to the different types of footware, and how many tanks and APCs can travel at more than 150 mph?
As Dave A has tried to point out, racing game developers are hit hard with a lot of coding demands. The game has to be able to load vast landscapes and have them race past at speeds of 200 mph or more, such as in the case of F1 cars and GT5's X1. After all, while you're racing your view is fixed, and the rest of the universe is doing all the moving. So as you're screaming down the Nurburgring, the PS3 has to stream tens of millions of polygons and megabytes of textures, and shove them past you at crazy speeds, while at the same time, calculating how well your car is doing with one wheel off in the grass because you messed up a turn.
I'm unaware of any shooter having to deal with this.
Face it Mulan, no one is taking you or your supposed points seriously. And since no one in PD is likely to act on your marvelous "vision," I think you've pretty much had your shot at convincing anyone. Nice try, now go race or play outside or something.
