And he further on adds that if it had been him, he wouldn't try an head on attack like that and also doubts to be succesful in launching a beeline straight attack like that. Because both Sasuke and Rock Lee have the ability to speed in that fast now and accomplish a thrust like that, but only one of them has the visual acuity to react to any counters.

The Chidori and Raikiri don't give people speed boosts. If Chidori gave Sasuke a speed boost, he wouldn't have to train for speed since Chidori would supposedly give that to him. The only Lightning Release tech that affects speed is the Raiton armor. The Raiton armor amps speed but also amps reaction, so it's kind of like the Sharingan where it can help the user react to things at that speed
