Although the thought of being stuck in a car seems unlikely, it's crucial to be prepared. Take, for example, a situation where your car is submerged in water; opening the doors becomes impossible due to water pressure.

So, what's the plan of action? According to the TikToker, escaping such a predicament is "very simple". She advises to fold down the rear seats and crawl through to the boot.

There, she highlights a "life-saving switch" which, when pressed, allows the boot to open with a single click, providing an easy exit route from the vehicle. With her expertise in driving tips and tricks, this particular video has already attracted over 23,000 views, sharing vital car wisdom with drivers everywhere.

This revelation comes after people just discovered the real reason behind those tiny black dots on car windscreens - they're not merely decorative, but serve a crucial function.

These black specks, known as "frits" or dot matrices, are typically found along the outer edges of the front windscreen, often adjacent to a black enamel band encircling the screen.

Windscreen specialists at Autoglaze clarified that these black dots are often "underrated" by motorists, despite their key role in "distributing temperature evenly to lessen optical distortion or lensing."

They elaborated: "This happens when the frit band (the solid black one) heats up much faster than the windscreen's glass, creating an optical distortion that makes either straight lines look curved or bowed inwards toward the centre."

So, these dots help mitigate this effect, enabling the driver to see clearly through the windscreen by "dissipating the heat and spreading it out evenly."
