Vehicle Reversing cameras, a real safety improvement?

Congratulations on a beach

Congratulations Jonny! You have the honour of posting Technology Bloggers 500th article – which is also your 125th! It is also the first post of Technology Bloggers fourth year. (Image Credit)

At the end of last month the National Highway Traffic Safety Administration (USA) finalized long-delayed rules that will require automakers to install back-up cameras in all vehicles by May 2018. This was a long fought battle, the auto makers not wanting to be forced to adapt such measures.

And we must consider the costs, possibly between $500 and $900 million a year, to be borne by the purchaser, manufacturer and of course the state. The legislation is aimed at avoiding death or injury caused when drivers reverse over their own children or the elderly (the main victims in such accidents).

All well and good I say, maybe the rules will save some lives, and we should bear in mind that they did take 10 years to pass. But how many lives will they save?

A Typical view in reverse

We have to bear in mind that auto-mobile manufacturers estimate that upwards of 60% of all cars would have had the technology as standard by 2018, we are talking about the remaining 40%, so an incremental improvement on an already rolling ball. But how many people are killed each year in the USA in accidents of this type?

According to this article, fittingly enough from the Detroit News, 60 to 70 lives a year would be saved if all the fleet had rear view cameras, but of course as stated above 60% would have already had the cameras, so the legislation itself would save about 15 lives a year and save 1300 injuries. But how many injuries and deaths are there a year in the USA?

On average in recently in the USA there have been about 35 000 deaths and more than 2 million injured in motor accidents. According to the US Census Bureau most of those were caused by speeding and alcohol.

Now I would question the rationale of spending the amounts of money required to install cameras in all cars when the number of lives saved is going to be so small. We are talking about between 15 and 25 million dollars per life, when there may be better ways of spending this money and saving more lives.

If we look at the legislation in context, I think there are other questions that need to be asked too. The US government Distracted Driving website offers another bewildering array of statistics and related information, with mobile technology use once more taking the blame for accidents. But we might imagine that it is illegal to text and drive, but it is not in all states. Several states still allow you to send a text message while driving. Texas for example bans texting for bus drivers and novice drivers, and in school areas for everyone, but I can drive and text in Texas perfectly legally. Arizona only bans bus drivers from texting, and in south Carolina there are no rules about using mobile technology while driving.

Although road deaths have come down dramatically in the USA, those related to driver distraction have gone up. This could be related to changes in how the statistics are reported, or might be related to increased usage of mobile devices, I cannot tell that from the data provided in the census.

A table is available here that summarizes the current situation.

As a quick comparison in the UK you can be charged with reckless driving if you are involved in any accident, and texting and hand held telephone use is against the law. If you are eating or drinking however this can also be taken into account, and there is research that suggests that eating and drinking while driving can dramatically slow down reaction time. Check out this article in the Telegraph newspaper.

So I want to ask a serious question about this US legislation that we could ask about a lot of other legislation. Do these new rules really make driving safer, or do they make us feel that we are safer, or do they just make us feel that we are doing the right thing?

I don’t honestly believe that this legislation will really make driving much safer for anyone, although this is of course my own opinion. I am not making light of accidents that involve reversing over children or old people, but there must be plenty of more efficient ways of cutting down road deaths than this (like taking action to deter mobile phone or texting use for example).

Calling While Driving

One of the problems with humanity is that we all believe that we can do things safely even if others tell us that they are not safe. People who drive fast do so because they are good drivers (so they tell us), people claim that they can drive while under the influence of alcohol or drugs when the statistics prove otherwise, and even making a call or texting does not distract some super-drivers.

Governments take some action in some form or other to try and stop people doing these things, but it is selective in nature. Let us take texting while driving as an example. In some countries it is illegal to drive and text at the same time. In the USA it is allowed in some states and prohibited in others. In some states you can talk on the phone, in others not you need a hands-free system.

The law though seems to be selective. Last week research published in the Science journal demonstrates that it is not holding the phone to text or speak that is the problem, it is the conversation itself that causes the distraction.

The research showed little or no difference between the rate of accidents when people are using a hands-free system and when they are physically holding the phone. The type of conversation does make a difference though, the more the driver has to concentrate on the subject matter or think before replying, the more chance there is of having a crash.

They also found that any type of interaction, even listening to the radio, effects reaction times and attention paid to the road. The radio is the least invasive because it does not require a response, but I wonder if listening to a news show or a discussion that you have to concentrate to follow causes more distraction, a logical line of thought would seem to imply so. Interestingly enough voice to text is the most dangerous type of technological interaction addressed.

So there are laws against texting, and not holding a phone (I must add not everywhere) but why not make speaking hands-free illegal too? And we should bear in mind that cars are ever more designed for connectivity, and that means distraction, maybe this should also be regulated.

Well that would require a change in business practices and take away personal freedom some might say, but we should remember that driving is not a right, it is a privilege that is governed by rules.

This is a serious piece of research that uses eye monitoring technology to measure distraction and driver awareness. The findings are clear and there is plenty of supporting data from other sources, but how would you feel about not being able to make a call at all though while driving?

At least your boss couldn’t call you while you were on your way home.
