My ride between two tollbooths was timed, and I received a speeding ticket in the mail. Isn't that illegal?

Can they prove YOU were driving??? Otherwise you loaned your car to someone who is now DEAD LOFL if they want to play games you can to I once beat a ticket for running a stoplight where there was a camera that took a pic of my jeep running the light I told them i was not driving when they asked who was i told them i didnt know its up to them to prove the crime I beat it
