+1, let them eat mirrors.
I am slightly surprised to find myself coming to the defence of Crazy Harry and co., but I think people have to be careful when claiming that cockpit view is the be-all and end-all of realism. Why is cockpit view realistic? Because the camera position in the sim is where the driver's eyes would be in a car. OK, cool. That's one aspect of realism. But in terms of peripheral vision, cockpit view on most reasonable FOV settings loses a lot of realism, because it makes the sim driver unaware of what's going on to either side, whereas the real car driver would be perfectly aware of the car coming up beside him.
A lot of virtual reality research (I could dig up some references if anyone cares) suggests that putting the camera behind the user's avatar leads to more effective control and movement in the virtual world, than does putting the camera at eye position "inside" the user's avatar. This is assuming display devices that cover less than 100 degrees of the field of vision. I'm not thrilled about this finding, but it seems real and reproducible.
Cockpit view would be close to perfect if you had about 5 monitors wrapped around your driving position. I can completely understand if people using only one monitor want to make a compromise between a realistic camera position and situational awareness. Chase view is one such compromise, and if people are going to use that view why should they be deprived of a mirror?
(In case anyone cares, I don't use chase view. Until recently I used cockpit view, and I'd still prefer to use cockpit view, but I was blown away by how many more FPS my crappy computer gets when I use the "wheels" view, so I am stuck with that for now.)
