Seriusly, if you cant filter information or you are not able to react to your surroundings please dont drive. Half a second of reaction time more is a lot when you are driving a 2 ton car with 100kmh around… that si rhe reason drunk driving is not allowed or driving while high…

With embedded stuff its still done like that. And if you go from the arduino functionss to writing the registers directly its a hell of a lot faster.
