This depends on: Amount of medical bills; Amount of time you have lost from work; wheter you will have permanent physical disabilities or not; whether you will be able to return to work; how old you are; how the quality of your life has been affected, i.e., what you can and can't do now (or in the future) that you used to do and enjoy before the MVA, and your pain and suffering. Most states do not allow you to sue for a specific amount of money, and just let the court (jury) decide.
Howmuch money you recover depends on all of the above, plus how much insurance did the other person have? How much did you have in underinsurance on your own vehicle(s) and how much does the other person have in personal assets beyond his/her insurance coverage. From what you say this sounds like seven-figures and up ($7M) - not settlement can be done without you personally accepting the amount offered!
