I reckon hi-viz gear can help a bit, but along with ATGATT, ABS, MSF, CBT, track day developed skills and the like, it is no panacea.
People who think their superior gear and skills are their guardian angel deceive themselves. Don't rely on the senses of others to avoid you.
Ride aware and to the conditions. It is your own attitude, senses, and common sense that will keep you out of trouble.
