In a rally car, you sit pretty much upright and tightly strapped back/in. I haven't used RBR in a while, but from what I remember the camera position was spot-on.
Exactly real. Why? Because you do not have 2 wheels in the car. The monitor is your windshield, the space between your monitor and wheel is the dash area, and the wheel you are using is the wheel. It gives the most real interpretation of driving a car from the driver's seat rather than driving from the back seat like default LFS.
You don't have two wheels... But some people don't have 200 pounds spare to give for a G25 or G27 and don't want to spend money on some cheapish shit that would die in two weeks so they play on KB, like me... That's why it is good to have a cockpit view with wheel visible...
BTW, when you use a wheel and a view where there is no wheel, you actually have no "real" dashboard, only the digital one, or you have to make/buy one to put between the wheel and the monitor.
Real life doesn't have a good sense of speed. Atleast not in my dad's BMW. Feels like you are doing about 70mph then when you look at the speedometer you are doing 110mph+.
Sense of speed completely depends on the car. In the Kia he had before hand at that speed (it almost got there one) it felt really fast but in his 3er it seems like a much lower speed.
