I hate that you can have assists on every car. A Mercedes 300sl shouldn't have abs and tcs and other assists. On modern cars it's OK but for cars which don't have assists it should be an upgrade in the tuning shop like in GT2.
While I do like your suggestion, I have to agree with Slip. I normally race with a G27 and I consider myself to be handy enough with any car on any tires... at least handy enough to be better than about 95% of people online. I normally enjoy shuffle racing and grip racing but I will use Skid Recovery Force when it's available as I'm very competitive and will use any advantage I can take if it means I'm competing for the win.
However I recently had two races in two different lobbies with the same car. My experience with the first lobby was fresh in my mind when I made the choice to use one of the Aids that I normally do not use in the second lobby.
The first lobby had dis-allowed every aid minus ABS. The track was Indianapolis Road, and the car was the Lancia Stratos. I found that with enough effort and careful application of throttle, I could drive the car effectively... but
any of even the slightest of bumps or general disruption of chassis balance/weight transfer would cause the car to go sliding around like it was on ice. I got a good start and had the lead, but all it took was one guy dive bombing me on the inside to pass me that got me spinning. I was frustrated and decided not to continue for the sake of my tranquility.
The next time I drove the Stratos was in an entirely different lobby almost a week later. This room allowed just about everything minus the driving line and Traction Control. The track was Clubman Stage Route 5. After a few practice laps with the Lancia with SRF on I made the choice that I'd rather contend for the win (since I'd already won two races and wanted to see how long I could keep the streak going) so I enabled ASM as well, since SRF didn't seem to be enough to really tame the Stratos. I did end up winning as the Lancia was a strong enough car to overcome racing with ASM on, but I felt bad for doing it.
The moral is that this is a game that many people play to enjoy, not to simulate or challenge themselves all the time. I wanted to race and enjoy the race and not be hampered by a very unwieldy car. So I used something that really wasn't a feature on the car and ended up winning as a result of it.
