Yes, but the perspective of a EV-certified Firefighter or Homeowners Insurance Provider's questions are not that important to Mercedes-Benz because you are not offering them money.

In general, per mile driven, gas powered cars burn about 40 times as often as EVs, and the real culprits are hybrids, which burn 60 times as often. And that are the numbers from insurance companies, which have to foot the bill. But how often do you hear from pundits how dangerous hybrids are compared to normal gas powered cars? Hybrids are now so ubiquitous, that people have accepted their existence. The same will happen to EVs, and fire fighters and insurance companies will find relief because car fires are not really an issue anymore, as the dangerous moving gas grenades are slowly fading from the roads.
