As the article points out, the fleet size of Tesla Semis is very small. And as this is the 2nd Tesla semi fire, this represents a much larger share of these trucks, than any single Mack Truck fire. If Mack trucks caught fire at these rates it may well make the news.
This would be roughly equivalent to 5,000 of them catching fire at once, scaled for the number which exist, so, yeah, might draw some comment.
Is there an article every time a Mack Truck catches on fire?

This is the second one of these to have blown up. It looks like about 200 exist. It is _notable_ that 1% of the entire installed base has caught fire.
