I wear high viz all the time but I still pretend that they don't see me whether I am on my motorcycle, scooter (when I had one), or my bicycle.
BTW, I've been riding since 1954 but I don't care how long you have been riding. High viz might help but don't depend on it, you had better ride defensible.
