Introduced in the ‘80s, it gives following drivers an extra visual cue to slow down, especially when tailgating.
It’s less about flair, more about function—breaking up rear-end collisions by lighting up in just the right place. It may be the least flashy light on your car, but it earns its keep.
11. Laminated Side Glass
When it comes to protecting passengers, laminated side glass is a game-changer. This multi-layered glass holds together in an accident, reducing the risk of injury from shards.
Originally used for windshields, its application to side windows adds an extra layer of protection. It’s like wearing a seatbelt for your windows.
Beyond safety, it also reduces noise and blocks UV rays. A trifecta of benefits! Laminated glass is an elegant solution to a dangerous problem.
12. Automatic Door Locking After Takeoff
You might not think much of it when your doors lock automatically as you pull away, but it’s more than a convenience.
This feature helps prevent accidental door openings, protects passengers in a crash, and even deters carjackings.
It’s a small moment in your drive—click—but it plays a big role in your safety bubble. The best part? You never have to think about it. It’s the automotive equivalent of locking the front door without lifting a finger.
13. Soft-Touch Dashboard Materials
Soft-touch dashboard materials might seem like a luxury, but they also serve a safety purpose. During an accident, these materials reduce injury risk by cushioning impact.
