Fine, in theory. Now try that when you're tracking a group of cars cresting a hill, swooping down towards you into a somewhat shaded area, and getting back into full sunlight as they drive away, and you want to grab the shot at the best moment (which depends on what the cars are doing). If I'm doing anything manually it would be changing the zoom to follow the cars. If I know just where I'll be taking the shot I'll turn off AE, anyway; you don't *want* exposure to change depending on whether your primary subject is a black car or a white car. If I have to use AE, though, I'll use the full multi-segment metering (not matrix metering - that's copyrighted); center-weighted metering performs significantly worse in this scenario.
