7 Vital Advances That Could Save Your Life

Every single time you get behind the wheel of your car, you’re putting your life in your own hands—and in the hands of each and every unskilled, distracted, and incompetent driver you happen to meet on the road. When you hear people claim that you’re more likely to die in a car accident than an airplane crash, it might be tempting to just write it off as hyperbole, but there’s actually hard science behind that claim. The fact is that people die in car crashes every day, and many times more are injured, but as technology advances, things are actually getting better.

According to NHTSA statistics, there were 1.58 fatalities per 100 million miles driven in the United States in 1999, but that number dropped to 1.27 per 100 million miles driven by 2008. Some of that can be attributed to crackdowns in the enforcement of drunk driving and seatbelt laws, but a huge part of it is also attributable to vital advances in automotive technology, and the steady adoption of those technologies across the industry. With that in mind, here are seven of the most important advances in automotive technology that might just save your life some day:

seat belts

The original technology: lap belts.

The advance: shoulder belts, seat belt airbags, etc.

Why it's so important:

Seat belts are boring and pretty much universal, so it may seem like they don’t belong on this list. If you were born in or after the 1980s, there’s even a good chance that you’ve never even ridden in a car that didn’t come equipped with this most essential of all safety features. But there was a time when seat-belts weren’t standard, and even when governmental regulations forced an industry-wide adoption of the feature, the first lap belts were only a pale reflection of the advanced safety restraints we enjoy today.

According to the CDC, seatbelts save well over 10,000 lives a year, and since 1977 this one safety technology has saved roughly 255,000 lives. So while “click it or ticket” may be the driving force behind some people grudgingly deciding to buckle up, wearing a seat belt is probably the single most important step you can take toward not becoming one of those 1.27 fatalities per 100 million miles.

The original technology: dumb airbags.

The advance: smart airbags.

Why it's so important:

Airbag technology has suffered from some bad press over the years. That airbags save lives is undeniable, but they’re also dangerous in some situations, and seating a child in the front seat of an older airbag-equipped vehicle can actually have fatal repercussions. However, advances in airbag technology have actually made them much safer, less likely to cause injuries, and even better at saving lives.

One of the most important advances is the smart airbag, which uses an array of sensors to determine when it isn’t safe to deploy. For instance, if a smart airbag determines that a passenger is below a given weight threshold, it will typically fail to deploy in order to avoid causing serious injuries or death. Other advances, like side curtain and rollover airbags, may save your life during a rollover accident by preventing your forcible ejection from the vehicle. More »

The original technology: stationary headlights.

The advance: adaptive headlights.

Why it's so important:

While some advances in automotive technology have been met with mixed results and unclear data, the jury is in on adaptive headlights, and they can definitely save your life—particularly if you find yourself on the road during the twilight hours. According to a study performed by the IIHS, vehicles equipped with adaptive headlights were involved in about 10 percent​ less accidents. More »

The original technology: manual cruise control.

The advance: adaptive cruise control.

Why it's so important:

The overwhelming perception of adaptive cruise control is that it’s nothing more than a creature comfort, or just one more excuse to be lazy on the road. And there’s some truth to that ​since it takes a lot of the guesswork out of using cruise control. However, adaptive cruise control is also an invaluable safety technology that can help prevent high-speed collisions.

For instance, if a car suddenly cuts you off, adaptive cruise control is capable of detecting the obstruction and slowing, or in some cases even stopping, your car. Of course, that leads us to the next potentially life-saving technology. More »

The original technology: based on anti-lock brakes and other systems.

The advance: collision avoidance systems and automatic brakes.

Why it's so important:

Sometimes human reaction times are sufficient to avoid accidents, and sometimes they aren’t. When they aren’t, collision avoidance systems are there to pick up the slack. These systems are often extensions of the same basic technologies behind adaptive cruise control, in that some type of forward-facing sensor is used to detect potential hazards in front of the vehicle. In addition to looking for vehicles that have suddenly slowed down, or cut in front, they are also on the lookout for debris, large animals, and anything else that you don’t want to run into. If an accident is imminent, a basic collision avoidance system may sound an alarm to alert the driver, while one that’s equipped with some type of automatic brake system may precharge the brakes or even apply them.

Automatic brake systems are also useful in stopping incidences of runaway cars—due to either operator error or mechanical malfunctions. For instance, if the gas pedal gets stuck for whatever reason, an automatic brake system may be capable of both applying the brakes and cutting the throttle to prevent the vehicle from careening out of control.

The original technology: some similarities to adaptive cruise control.

The advance: lane departure warning systems.

Why it's so important:

Although lane departure warning systems are seen as an annoyance by some drivers, this is a technology that is absolutely capable of saving lives. One of the most dangerous types of accidents you can experience is a rollover, and tripped rollovers often occur as a natural part of run-off-road accidents, where a vehicle veers off the road. If a lane departure system detects that a vehicle is straying from its lane, either into traffic or off the road, it can either sound an alarm or take corrective action. Potentially annoying, but also potentially life-saving. More »

The original technology: built on anti-lock brake and traction control technologies.

The advance: electronic stability control.

Why it's so important:

Electronic stability control (ESC) is possibly the most important, life-saving technology, behind seat belts. In fact, the only reason that anti-lock brakes are now standard on all new cars is because new cars are required to include ESC. In fact, if you’re looking to buy a safer used car, the number one recommendation from the IIHS, in terms of safety technology, is to look for one with electronic stability control.

Of course, electronic stability control would be nothing without the related technologies of anti-lock brakes and traction control systems, both of which are intrinsically linked to ESC. In fact, despite the fact that ABS is itself a life-saving technology, it didn't become required equipment in passenger cars until the introduction of ESC mandates. More »
