None of them are blind, I dont understand how you guys think that all the obstacles I place are blind? I would not place them if you cant react to them.

Well there's some pretty blind obstacles in several turns. Also, the obstacles take up quite a bit of the track so sometimes memorization is required to react to some of them on time.
Playing this level by staying on the road for brief moments and leaving once an obstacle shows up is becomes more fun, but I doubt that was the intention.

the obstacle placement makes this more fun to play off-track than on it
