Meh, I think it's only as strange as you want it to be. Why should it matter if a driving simulator have unrealistic aids if it also offers the "realistic" option? For one the automatic in the game isn't even realistic as is any other racing game, cause we all know automatic driving in real life doesn't red line shift unless you floor it. It's a game, that millions and millions play. I say let there be options.
And actually, I've had casual "friends" struggle to control some cars (e.g. Zonda R or any high power car with low grip tires) with TCS/ABS/ASM on. Heck, even with the SRF, it was still a challenge for them. Plus TCS is a heck of a pain too when set too high and ASM limits the power. SRF and RS allow the more casual players to enjoy the cars full potential without having to be too technical with throttle control. Like said before, as long as it's not "forced" upon us, what do us "hardcore" players have to worry about if we can just turn them off?
