I hope the people getting calls from these cars are trained to deal talking to hurt people, but I suppose the agency the manufacturers have outsourced this service to can recruit 911 operators for a little better pay. They can say on the phone "This is X from Mercedes help center" but I'm speculating that X's work console displayed "Connecting you with a car in need of assistance. Car brand: Mercedes" a few seconds before.
I wonder if the more expensive car brands can jump the queue of getting help after an incident.
