Camera needs work in terms of leaning into turns as well as pulling away when speeding up. Car’s mechanics don’t change with speed either, turning should get more/less difficult depending on your speed for example.

Thank you rask I’ll try to implement these suggestions

Trail thingy that show fast lap trajectory is pretty cool.

However i noticed that shadow and camera behavior.
