particularly on the second video at about 16 seconds. the last turn after the straight. you should have slowed well before that turn. you could have been turning as you were passing the cone rather than having to stop. turn. then accelerate again. that should help out significantly. it's hard to not just go fast past every turn. you have to learn to slow down before the corners. it goes brake, turn, accelerate out of turn...

LOOKS LIKE FUN THOUGH! GL with it.
