Your driving is a little choppy, but with a little improvement will be great. By choppy I mean the turns aren't completed too smoothly, instead of immediately jamming the thumbstick to the direction you want to turn, slowly move your thumbstick to the direction you want to turn, and when exiting the corner, slowly bring it back to the middle. It may not sound like much help, but trust me, in the long run it pays off. Since the sticks are analog, just moving the stick a little to the left of center for a left turn eliminates the swerving you'll sometimes face with jerky steering.
Great video btw. 👍
