Sonic speed is greatly decrease in stages so that the player would be able to see and control Sonic in gameplay. If you look at games with measurement of speed like Sonic Unleashed, it shows that the light speed dash, which makes Sonic moves at the speed of light, is actually slower than when Sonic is boosting, meanin that Sonic is faster than the speed of light. So I think that Sonic would be going through places around speeeds like that.
