In that situation, pull into a police station. (Unless you are in San Francisco, LA, Chicago, New York, Philadelphia or Atlanta)
I had to do that one night.
I was driving in an unfamiliar area of Las Vegas where there was road construction (duh, there’s always road construction in Las Vegas) when I cut off another driver. Next thing I know, she is following me and tailgating me so closely I couldn’t see her headlights. The only police substation I knew of was near my neighborhood so it took me nearly 15 minutes to get there. She followed all the way until I pulled into the parking lot. I waited a few minutes and then took a round-a-bout route home to make sure she wasn’t following me again.
