Some other countries ( Brazil, for example ) require fire extinguishers in the vehicle. They are normally mounted in front of the front passenger seat on the floor. I was looking for one for my car, and after doing an internet search, found out you could get OEM mounting brackets for common sizes, but they are not readily available in the U.S.

I do carry a fire extinguisher, unfortunately, it's not mounted. (Yes, the top is protected!). I also carry a set of gloves, per the training I've had before. I will add one of those rescue knives.
