What does the license plate number ending in 175 mean?

It has no specific meaning, just a number. I heard a joke before. A car owner with a license plate of 00544 (I’ll try it) was rear-ended. He got out of the car to check and found that it was a car with a license plate of 44944 (try it). The license plate I just tried got hit. Both families laughed. This is just a joke and has no practical significance.
