no you haven't you just think you have - people simply don't realise what's happening.
In the moment, most drivers don’t have time to consciously think about road safety. ethics or weigh their options when faced with an unexpected obstacle like a suddenly swerving m/c or a dog. Their response is often instinctive and driven by emotion rather than deliberate thought. The emotion is one of self-preservation. So - when drivers see a vehicle or animal suddenly on the road, their brains trigger an automatic, split-second response based on shock or fear and preservation. They may subconsciously think of avoiding damage to their vehicle or even protecting themselves The instinct to avoid a collision kicks in almost immediately, like any other sudden danger. The attack ode you describe takes a few more nano-seconds by which time the crash has usually happened. If it hasn’t then you are considering where to drive and this could be construed as deliberate and therefore dangerous driving.
