Hi, i was involved in a car accident with lyft driver last week thursday around Brookes drive MarylandThe driver suddenly started convulsing

You probably have a good case against Lyft, and the driver, if the drvier had a condition, which he knew, or should have known made it dangerous to drive.      You will need to do extensive investigation into the Lyft driver's medical histroy.    I would suggest you contact a lawyer as soon as possible to discuss the details, as these cases can be complicated.  The first consultation is always free, and you do not pay a fee unless you recover money.
