What kind of settlement would I expect if the hood flew open and crashed into the windshield, shattering glass in my eyes, my clothing and my body?

I am so sorry to hear about your accident! First off, were you working or just test-driving a new car? If you were working, this would be a workers' compensation consideration and you should contact a Certified Workers' Compensation Attorney. Otherwise, it's all going to depend on medical bills and your ability to work. Your best bet is to contact a Personal Injury Attorney as soon as possible to find out your options.
