Firefighters are sounding the alarm because this isn’t a freak accident; it’s simple physics meeting everyday carelessness. Clear plastic, water, and direct sunlight can align just right to focus a burning hot point onto your upholstery, especially on dark seats. Even a brief stop in a parking lot can be enough if the angle of the sun is perfect and the bottle is positioned just so.
The fix is almost embarrassingly easy compared to the damage a fire can cause. Treat loose bottles like a risk, not clutter. Keep them out of direct sun—tuck them in the glovebox, under a seat, or switch to opaque or insulated containers that can’t focus light. One tiny change in habit can mean the difference between a safe drive home and watching your car fill with smoke while sirens close in.
