You spotted the hazard — a deer stepping onto the pavement two seconds ahead, gravel across your lane, the car door opening into your path. Your scan worked. Now comes the response, and this is where riders in straight-line accidents fail: they had to think about what to do first, and physics collected the debt while they were thinking.

Every input you make — braking, accelerating, steering — draws from the same finite pool of available traction. The pool does n...
