I was driving a rental car in Phoenix and saw a flash of light from a white van. At this time 3 other cars were passing me and I assume it was the other cars. I received a notice in the mail from Hertz renter car that I need to pay a fee to waive their responsibility on a citation. I have not seen or been issued a citation. When I called Hertz they said they do not have that information available. My questions are what should I do? If I do not pay Hertz what are the ramifications? Will the state eventually go after me? Will this affect my driving record? How do I prove that the cars next to me were in fact the ones speeding and I was simply driving the speed limit?
