Want to learn car control with a controller the hard way?
Play Project Cars 2 with a controller and no guide on how to set it up properly to work with a controller. I've been playing the game for years and have it down with a controller, then it rains or snows and I snap oversteer right into every barricade.
Project Cars 2 does have several assists like the driving line, traction control and stability management, but they are more "you won't spin out every time you push the go pedal" than "We'll do it for you". Project Cars is better played with a wheel.
If you want to ease yourself into a sim style game, Forza Motorsport 7 can hand-hold you a lot better than Project Cars 2, and can be effective at making the red car behave more like the green car so you can concentrate on braking and cornering lines instead of keeping traction in and out of the corners. Then when you're comfortable, you can start shutting off assists like traction control/stability management and turn on things like sim steering/tire wear and simulated damage. There are even assists to equalize the off track traction so that when you drop a tire into the gravel the car doesn't get yanked off the track by the difference in surface friction.
The most important thing for people starting out with sims to do is use the brakes. It may seem like you're going slower but a stable car is a fast car. Every time you upset the car's balance of break traction you are losing time. Entering a corner with too much speed will put a lot of heat into the tires and reduce both speed traction on exit. That in turn causes the first part of the next straight to be a battle to reign in the rear end which slows you down even more and wears out the tires even more. Corners have an apex, you shouldn't be accelerating before this point and you shouldn't really be just flooring it at this point either. As the car straightens you increase throttle. With enough practice you'll be on the edge of traction without stepping out the rear end.
Think of it this way for starters, as you turn the wheel, the amount of throttle should be reduced equally. As the wheel straightens throttle can increase. The characteristics of each car dictate how much, but it's a good place to start from.
