Excuse my French if I seem a bit categorical and pessimistic here.
But the best help you can give yourself and not least your fellow road users out in traffic is to sharpen your senses, your reflexes, your vision, your reactions. Every single day.
My view and observations since the first cars with lane assist came to the consumer market a couple of decades ago with the Nissan Cima, Honda Inspire, Mitsubishi etc., have been that it makes people lethargic faster than they realize and far more than many even realize. In addition, at the same time the smartphone came and today in traffic I feel that it is almost every third person or more you can clearly see their eyes are directed at the phone. And then the increasing impatience.
Of course it is convenient and feels safe when the automatic emergency brake activates itself, but bottom line in the use of your senses you could, just with driving skills from the driving instructor's Schoolyard.
