Was i supposed to drive faster?

I was once driving in a neighborhood at night and some cop started tailgating me so I sped up to 30mph on a road that had a speed limit of 25mph. He was still tailgating me so I sped up to 35mph. He was still tailgating me so I sped up to 40mph....to no surprise he was still tailgating me so I started getting nervous and I signaled to make a turn on some random area of the neighbourhood I had no intentions of visiting. He didn't have his lights on or anything. Would I have gotten in trouble for speeding if I sped up any further? Was he just trying to mess with me or something?
