Its4women.ie - Would you trust a car that can drive itself ?

 

At its4women.ie car insurance we are always looking for ways to promote safe driving. Every year, 1.3 million people are killed and 50 million injured on the world's roads.

 

Most people rate their ability to drive a motor vehicle very highly, but would you allow a car to drive itself ?

 

Carmakers are racing to create a vehicle that will never crash, but can it be done and will drivers accept a computer that overrides their driving?

Less than 30 years ago, "clunk clicking" ourselves into our car seat belts seemed like the cutting edge of road safety technology.

Since then, we've seen airbags, anti-lock braking systems and crumple zones fitted to new cars.

Now the arrival of crash avoidance technology - systems that can alert drivers to danger and even take action to prevent accidents from happening - promises to cut the number of crashes on our roads.

So confident is Volvo of the power of its technology, it has pledged that beyond the year 2020, no-one will be killed or seriously injured in one of its new cars. In essence, the Swedish manufacturer is aiming to build a vehicle that will fully protect its occupants and crash less.

"The major cause of crashes is the driver not paying attention or drivers being distracted. This technology is giving cars eyes and knows when the driver fails," explains Thomas Broberg, Volvo's senior technical adviser for safety at the company's research centre in Gothenburg.

Other carmakers are making similar commitments. Toyota says it is aiming for zero fatalities and injuries, although it has not yet said when that goal would be achieved. And Ford is already marketing its new Focus - with its self-proclaimed "intelligent protection system" - as one of the safest vehicles on the mass market.

So what is the latest technology and can it really prevent crashes?

Systems that monitor blind spots and track the alertness of drivers, and electronic stability control - which can detect and help prevent a skid - are already being introduced to many new vehicles. Some cars also now have adaptive headlights that improve night-time visibility by pivoting around bends, as well as instruments that warn of a potential collision or when a vehicle drifts out of a motorway lane.

With up to 70% of crashes caused by driver or rider error, these measures are widely expected to help reduce the number of collisions.

One study by the US Insurance Institute for Highway Safety has estimated that four of the currently available features - lane departure warning, forward collision warning, blind spot detection and adaptive headlights - could prevent or mitigate one out of every three fatal crashes and one out of every five crashes that result in serious or moderate injury.

While most people would welcome measures that assist motorists to make wiser decisions, systems that actively intervene in the driving process cause more controversy.

Research is being done on autonomous braking technology, which can stop a car when other vehicles or obstacles get too close, and lane-keeping support, which applies a correcting force through the steering if the driver drifts out of their lane.

The manufacturers are also developing adaptive cruise control, which can automatically maintain a safe speed and distance from other vehicles, and intelligent speed adaptation, which can, in its most active form, prevent a driver exceeding the speed limit.

 

Research into effectiveness is in its infancy. A 2008 EU study by the Finnish VTT Technical Research Centre found the most promising technology after electronic stability control - compulsory in new cars in Europe - was a system preventing a driver straying from a motorway lane. It estimated that they could reduce deaths by about 15%.

The same researchers found that functions warning drivers they were exceeding the speed limit and of other potential hazards would cut fatalities by 13% and that emergency braking assistance and driver drowsiness warnings could potentially reduce deaths by 7% and 5% respectively.

However, other studies have been more optimistic. The US Highway Loss Data Institute found that 27% fewer insurance claims were made against cars fitted with Volvo's City Safety system, which uses autonomous braking technology to avoid front-to-rear low-speed crashes. And University of Leeds research has found that speed-limiting technology can reduce crashes causing injuries by almost 28%.
