Flames on sight lol. Nah fr doe, Amaterasu is initiated by the user gathering chakra in his eye and focusing on a target, causing the black flames to ignite. Unlike normal flames, these flames lack momentum and physical properties, instead possessing a more parasitic nature, spreading through anything it comes in contact with, albeit slowly. As we know, while dangerous, they aren't unavoidable, if you are able to move fast enough you can evade them at their point of ignition. Another counter to this is if you are able to sense/detect the the build up of chakra, and can produce a technique that allows you to defend swiftly, iss possible to "push* the flames away in a sense but, this usually only applies to tangible defenses that form from underneath your skin in a sense, you can't create something in front of you as the flames are ignited on your body. Energy based ( lightning/fire ) defenses are useless against these flames.
Fortunately doe, these "weaknesses" of Amaterasu don't really apply to Sasuke as he is able to control the flames at will, shaping them into different constructs, and even firing them as projectiles with speed and force. He's also able to use the flames in conjunction with his Susano'o.
