Here is a situation I had when I wasnt carrying. I was heading home from campus this evening. I decided not to carry today because the two places I was going to (the university and pizza hut) had banned fire arms. I live in ohio in case anyone is curious about the laws. So I was heading home on the freeway when someone comes up on me at a high rate of speed while I was in the right/slow lane. Then they start tail gating me. After a minute or so of that they decided to pass me on the right using the exit lane. While they were doing so, they almost clip me and I instinctually honked my horn, They immediately tried slamming on their brakes to try to get me to wreck with them. I avoided the wreck and got over one lane. So did the other person and tried to wreck me again. So I shifted lanes and tried to speed up to get a few cars between us but the other person did the same. So we went back and forth between speeding up and slowing down. At this point my heart was pounding because this person would not let me loose them and I did not know if they were armed and meant me harm. My next instinct told me to get off the highway because how easy it would have been to wreck. So I did my final speed up and other person did as well and got ahead of me. I checked for other cars and got off at the last minute in an area I knew very well. The other person tried pulling off to the side of the road and putting it in reverse to get to the off ramp. I had to wait about 10-20 seconds for the light to change and it felt like forever. I began weaving through traffic like a mad man to put cars between me and the other person if they were still following. Each light I hit, I made sure I had some sort of escape route. After a few times of doubling back I was sure I lost the person but I doubled back one last time make sure. During this ordeal, I thought of calling the police but I wanted my full attention on driving so I didn't wreck. Also it would have taken a few minutes for police to get to a situation that could have ended badly in seconds. So is there anything I could have done different?
