15 ’90s Vehicle Safety Features That Are Obsolete
In the 1990s, automakers introduced a wave of safety features that were considered cutting-edge. While many laid the foundation for modern systems, several have faded away as technology and standards improved.

The 1990s saw major strides in automotive safety, with manufacturers introducing features that were considered innovative at the time. However, technology has since advanced, making many of those once-praised systems outdated or unnecessary. Some were phased out due to improved alternatives, while others simply did not stand the test of time. Exploring these now-obsolete features gives a clear view of how far automotive safety has come.
1. Automatic Seat Belts

Automatic seat belts were installed in many cars during the early 1990s to comply with new regulations. These belts would slide into place when the door closed or the ignition was turned on. Although designed for convenience, they were often more frustrating than helpful. They could jam, trap clothing, or even cause minor injuries. Airbags and better-designed manual belts eventually rendered them unnecessary.
2. Driver-Side Only Airbags

In the early ’90s, many vehicles came equipped with a single airbag on the driver’s side. This was a major leap forward in crash protection at the time. However, it left passengers without similar safeguards. Dual front airbags soon became the standard, offering balanced protection. Today, cars typically feature multiple airbags throughout the cabin.
3. Rear Window Brake Lights Without LED

High-mounted brake lights became mandatory in the late ’80s and were widely adopted by the 1990s. Most used traditional incandescent bulbs, which were slower to illuminate. Modern systems now use LED technology, which activates faster and lasts longer. The old bulb-based systems are largely obsolete. LED lights have become the new norm in safety lighting.
4. Side-Impact Door Beams

Many ’90s cars promoted reinforced door beams as a key safety feature. These metal bars helped absorb energy during a side collision. While effective at the time, they have been surpassed by advanced crumple zones and curtain airbags. New structural materials also provide better impact resistance. Door beams alone are no longer seen as sufficient protection.
5. Traction Control with Limited Sensors

Basic traction control systems in the 1990s relied on rudimentary wheel speed sensors. They could reduce engine power but lacked real-time precision. These early systems often overcorrected and disrupted the driving experience. Modern stability control systems use faster processors and more complex algorithms. The original versions have been replaced by more refined technology.
6. Early Anti-Lock Braking Systems (ABS)

ABS became more common in the ’90s, improving braking performance under slippery conditions. However, early systems were prone to pulsing and were not always reliable. They could confuse drivers unfamiliar with the pedal feedback. Current ABS designs are smoother, smarter, and more effective. The old systems are now considered outdated by comparison.
7. Manual Headlight Adjusters

Some cars included dashboard knobs to manually adjust headlight angles based on vehicle load. This helped prevent blinding other drivers when carrying heavy cargo. However, drivers rarely used them properly or even understood how they worked. Today’s headlights automatically level and adjust based on sensors. Manual adjusters have all but disappeared.
8. Basic Keyed Ignition Locks

Standard metal keys with simple tumblers were the norm throughout the 1990s. These locks were vulnerable to theft and easy to duplicate. Ignition systems today use encrypted key fobs, immobilizers, and push-button starts. Vehicle theft prevention has improved significantly as a result. The old keyed ignition has mostly been phased out.
9. Seatbelt Reminder Chimes Only for Drivers

Vehicles once included chimes that only alerted the driver if their seatbelt was unfastened. This ignored the presence of unbuckled passengers, especially in rear seats. Modern systems include sensors in all seating positions. Visual and audio alerts now help ensure everyone is buckled in. Single-seat reminders are no longer adequate for safety compliance.
10. Passive Headrests

In the 1990s, headrests were fixed and primarily designed for comfort. They provided minimal protection against whiplash during rear-end collisions. Active head restraint systems today move forward during impact to support the head and neck. This greatly reduces the risk of injury. Passive headrests have been improved or eliminated in newer models.
11. Child Safety Lock Levers in Rear Doors

Rear door child safety locks were activated using a small switch on the door’s edge. Parents had to manually flip the switch to prevent children from opening the door. While still in use, newer systems integrate child lock functions into electronic settings. They can now be activated from the driver’s seat or key fob. The old mechanical method is becoming less common.
12. Manual Rearview Mirrors with Night Mode Tab

Rearview mirrors often featured a manual tab that reduced glare from headlights at night. Drivers would flip the mirror to dim the reflection manually. Auto-dimming mirrors using sensors are now more common and convenient. These adjust automatically based on ambient light. The manual tab has faded from most modern cars.
13. Airbag Shutoff Switches for Passengers

Some vehicles had a physical switch to disable the front passenger airbag. This was intended for child safety seats, but it required drivers to remember to activate or deactivate it. The risk of human error was significant. Current systems use sensors to detect passenger weight and position. Manual switches are rarely used today.
14. Simple Crash Frames Without Energy Absorption

Crash frames in the 1990s were built for strength but not necessarily for energy distribution. As a result, impacts could still transfer significant force to occupants. Modern crumple zones and safety cages are engineered to absorb and redirect crash forces. They reduce injury risk more effectively. The old-style frames are no longer sufficient by current safety standards.
15. Headlight-On Reminder Buzzers

Buzzers that warned drivers their headlights were still on helped prevent drained batteries. While helpful, they were often loud and unpleasant. Today’s systems automatically turn off headlights or use timers to prevent battery drain. The buzzer has mostly been replaced with smarter light management. What was once a helpful alert is now outdated.
