"The speed at which the Chidori is performed, despite being one of its greatest assets, also represents one of its biggest drawbacks: users move at their target so fast that its causes a tunnel vision-like effect for them. Because they charge in a straight line it is easy for opponents to attack them, and because of the tunnel vision it is difficult for the user to see these attacks, much less react to them. For this reason, most ninja cannot use the Chidori safely.[10]  However, a user of the Sharingan can overcome these drawbacks due to its heightened visual perception preventing the tunnel vision from occurring and its predictive capabilities making it easier for the user to avoid counterattacks."
