Lately I've noticed a lot of cars driving with fog lights on, especially during the day in clear weather. It seems newer cars are sold with fog lights but without turn signals as more people use fog lights than directionals. This morning at 6am on a 10 mile drive I counted over 30 cars with fog lights on. Keep in mind it was clear, no fog or rain or any other weather issues. Why use them? Are they on auto on some vehicles? It's like turning on your wipers when there is no rain.
