Haven't heard of that one before. I don't see how he would prevail on suing you for his emotional distress when abortions are legal. Further, how could he prove you would have been able to naturally carry the pregnancy to term.
If your friend had your permission to drive the car, then you can be held liable. But as the other attorney indicated, let your insurance company defend you. You need to make sure you send notice of the complaint to your insurance company and make contact with them.
Yes you can be held liable if they are able to identify your car. If you are asking this question, sounds like it was more than a mere bump to the other car. I would imagine the tavern had security cameras, if they did then the person that was "bumped" can view the video and make a police report and quite possibly identify your car as being the one that bumped into his/hers.
Pain and suffering is determined by how much pain and suffering you encountered as a result of the injuries. It is not restricted to a diagnosis. Pain and suffering is determined by how much work you lost as a result of the pain, how much pain medication you had to take as a result of the pain, how frequently you visited the doctor as a result of the pain and what other treatment you received in an effort to alleviate the pain. The adjuster will look at all of that. If there is not enough...
It will be the insurance policy that was in effect at the time the car was insured during the MVA. I would recommend contacting an attorney and that insurance company that was in effect at the time of the MVA.
