thanks for the feedback! this is most probably a side effect of the top down view. realistic physics seem very weird, it's so easy to underestimate your speed. the tires have realistic grip budget, and quick steering inputs easily overload the tires. try turning back steering assist if you are on the keyboard. it limits your steering inputs so they always try to remain under the limit the tires can still maintain. and if you are seriously interested, press F2 in the game, and try fiddling with the physics, you might be able to tune the simulation better than myself.
Thanks, I was able to make the car controllable with the help of the F2 tuning menu. You're right that keyboard input makes everything too instant, so I slowed the steering speed all the way down so the tires do not lose grip instantly. I also shifted the weight a bit to the front for better steering and grip. However, I think brake tuning would be good because currently the brakes are too powerful and I need to smooth them out.
