I'm a software engineer not a firefighter, but my understanding is that it's significantly an experience thing. Lithium battery fires clearly aren't trivial to deal with and do burn hotter than petroleum fires, but they're also very much less frequent and firefighters are learning how to handle them.
I'm not sure what the specific issue would be with race tracks. The average road course is very open and a very controlled environment; if you had to deal with a car fire, it's probably among the best places to do so, thanks to lessons learned in the blood of previous generations of drivers and track workers.
