Nice though but swerving to avoid a collision is part of your sympathetic nervous system, and you, like most others, have virtually no control over it. If we are walking towards each other and I reach into my pocket and throw a handful of change towards your face you will squeeze your eyes together, pull your hands up, turn your head to the side, and make a funny face. You are wired that way.
Can the same system be reprogrammed? Yes, to a limited degree. It takes a ton of work and must be practiced and rehearsed again and again. Once you break the cycle, the system defaults to it's original settings.
