People do realize how much work it takes to make something like this?
I've purchased "car controllers" in Unity for $200
If i can get this to work on Unity 2020.3, I'll donate more for the work already done. (Since my recent purchases require Unity 2020.3 )
It's worth more than $350 but not affordable to most people.
I hope you take this to the Unity store!
Get paid for your work!
