Oh man - sorry to hear this happened to you. I had something similar but without any really bad consequences recently. I was turning left and someone came up to the opposite stop sign after I'd started across. I thought I made eye contact with her too, but right about when I was just in front of her she gunned it and rammed me - fortunately slowly and when I yelled (and probably her kids in the back seat yelled too….) she hit the brakes, so she just bumped me.

Don't let any police officer tell you otherwise - a driver exiting a driveway does not have the right of way a MUP is treated like a sidewalk in this case and the driver has to come to a full stop, check for pedestrians and yield.
