It's true that in its current state it needs quite a few fixes. Personally, I'm enjoying it, but I'd emphasize fixing bugs like the third-person camera visibility issue. It always seems to snap at the track's edge for no reason, and you have to constantly push the right joystick because it doesn't save your position throughout the entire session.
There's another bug where jumping off a ramp prevents you from performing acrobatic tricks no matter how many times you press the corresponding buttons, forcing you to repeat the same ramp or jump at least three times to clear the sign.
Another bug is on one of the ramps in the already implemented stunt circuits with blue circular rings. There's a really bad ramp that throws you into the crashed state when you were simply trying to jump. It also has that vacuum cleaner physics that keeps you stuck to the ground instead of launching you in a straight line and landing like the realistic physics it currently lacks.
I've seen in some videos that the AI couldn't care less about the obstacles you put in the middle of the road; it just drives right through them or crashes into them, only to reappear further ahead and continue as if nothing happened. It needs a lot of work to actually give you a real challenge, unlike what they have now, where right at the start of the race they give you a boost worthy of a hacked kid, leaving you in last place for 30% of the race simply because you don't have a turbo boost.
