Interpretation
Comparisons to Conventional Vehicles Interpretation
While the press fixates on the occasional dramatic electric vehicle fire, the truly flammable elephant in the garage remains the internal combustion engine, which statistically torments its owners with a far greater, albeit less newsworthy, frequency.

Interpretation
Severity and Damage Interpretation
Despite their green credentials, hybrid car fires pack a surprisingly high-voltage punch, causing greater damage, longer firefights, and a stubborn tendency to reignite, proving that when they burn, they burn with a vengeful and expensive intensity.
