How should a Florida driving instructor teach students about the dangers of sun glare, which is particularly intense in the state?

1. Sun glare is not a significant hazard in Florida
2. Teach students to use sun visors, wear polarized sunglasses, keep windshields clean, increase following distance, and slow down when sun glare reduces visibility
3. Tell students to close their eyes briefly when sun glare is intense
4. Only discuss sun glare during winter months
