Will it be okay if I park my car on top of artificial grass?

I am not sure if I can park my car on my newly installed artificial grass.

I won’t recommend you to drive or park your car on artificial grass surface, the tires twisting motions and frictions will be very likely damage the turf. However, designs with artificial grass fits in between pavers on a driveway will be just fine as the contacts of tires will be mainly with pavers instead of artificial turf.

I also think that artificial grass is kinda slippery for the car's tires.

You know what they say, It's better to be safe than sorry. I will surely follow this advice.
