Is This Retired Firefighter's Claim About Putting Out a Car Fire Correct?

[u/AffableEffable]

Hi, I ran into this discussion on twitter, and most people in the comments were really mad at the ELBainter person (who claims to be a retired firefighter). I know absolutely nothing about any of this, so I was curious: are they right and the people there are just stupid, the opposite, or something in between?

Spot on take. If no one is in imminent danger let it burn and wait for los bomberos to show up and put it out. Two dry chem extinguishers isn’t going to do much to protect against potential exposures either unfortunately.
