I hate that as well. Not everything is hard. Anyone can drive a GT3 and that's how it's designed. If you're struggling to drive a GT3, that doesn't mean the game is good. In fact, that means either the game is inaccurate or you're too much of an idiot for SRO to idiot-proof you. Realistically, I could (with decent physical condition and a bit of practice) get somewhere near to a time I'd achieve on a game because the relative easiness of the GT3 spec cars. It's nowhere near the times of Andy Soucek or Maxime Soulet but that's how it's meant to be.
Many cars in game are difficult in PC1 when you remove the now resolved issues of the car over the limit. The 98T is an absolute monster with a lot of HP and not a lot of weight and it wants to spin the wheels every single time you put the power down and a good driver will learn to manage that whether IRL or in game. I hate that statement.
What I find a more reasonable statement would be is "the only cars that are difficult to drive in a sim should only be difficult because that car is difficult to drive IRL."
