Couple minor things.
On all of the lane change cones (where you have 2 cones set-up where you need a quick jerk of the wheel). It appears you're turning in too late and falling behind.
Ideally, you want the car to be turning way before that cone...it appears you're waiting until you get to that cone to turn, which kinda makes you shoot wide, lose speed....etc
It's hard to realize, but here is an example of turning before the cone and holding that steering angle:
You want to turn to HIT the cone (but in reality you'll miss it)
Coming up to the cone, and already turning to go around the cone:
And getting around the cone. The car is carrying speed, so you anticipate the car pushing out and hope you come close:
It's tough to do, and will take time. I was TERRIBLE at this before.
BTW - When you see a downed cone (I saw one in one video at the very end). STOP and point it out! You get a free run for it! Sometimes people don't notice the downed cone until you pass, and they may call that cone on you.
PS - Cone marks clean up fairly easily
