Driverless cars are quickly becoming a reality, as, increasingly, manufacturers are investing huge amounts of time and money into the research and development of autonomous vehicles.

The UK is hoping to be at the forefront of driverless car uptake. In fact, in this year’s financial budget George Osborne announced a planned £100 million investment into driverless cars. With cars being tested in four locations across the country, it is only a matter of time before they become commonplace on our roads.

The rise of the autonomous vehicle is certainly exciting; it presents the greatest change to our roads since an engine and a steering wheel made the horse and carriage redundant.

There are some obvious gains to autonomous driving, but there are also some gaps in the technology, giving real cause for concern. Let’s take a look at what seem to us to be the biggest pros and cons of driverless technology.

Pro #1: More free time

The cars will know where other cars are, so the risk of crashing is hugely minimised, and you’d be able to get other stuff done while en-route to wherever you’re going. You know that relaxing feeling of sitting on a train and reading a book, listening to music or catching up with friends? You would be able to do all that in your driverless car, and have a much more pleasant experience. You could even sleep on your way to work, or drink on a night out and still be able to drive home! Basically all of these options will lead to drivers becoming way more chilled and calm. Goodbye, road rage!

Pro #2: Safety gains

The vast majority of car accidents occur as a result of human error. The number of crashes will decrease significantly as driverless vehicles would be able to communicate with one another, identify the position of other vehicles ahead, and most importantly, will control themselves, rather than being controlled by drunk or tired drivers. These safety gains would have a knock-on effect on your insurance, too, making it cheaper.

Pro #3: No more ownership

Insurance might get cheaper, but driverless technology could also lead to the end of car ownership completely. Think about it; if you could take a taxi everywhere, you probably would. What’s stopping you? The cost of paying someone to drive that taxi often outweighs the costs attached to owning a car over a period. If you remove the driver, the relative cost of owning a car and renting one is flipped on its head. It is likely to become cheaper to summon a car to take you to your destination, than it actually being ‘yours’.

Pro #4: No more bumper-to-bumper traffic jams

Worrying about traffic congestion will be a thing of the past. Driverless cars will be able to talk to each other, to figure out the quickest route to go, and to know to avoid areas where their robot pals are taking their human passengers.

Pro #5: Driving available to everyone

Driverless cars also present an exciting prospect for the elderly, disabled, and even children, all of whom may not be able to drive at the moment, but would be able to in an autonomous vehicle.

So what’s not to love?

While driverless technology is undoubtedly exciting and presents a whole host of positive outcomes, there are still some serious creases that need to be ironed out before driverless cars can become a viable option on our roads.

Con #1: Risk of hacking

One of the main cons that have got people talking is the risk of hijackers hacking driverless cars by interfering with their code. Cyber terrorists would have the potential to bring entire cities to a standstill, to kidnap people, or even to commit deadly terror attacks. It is likely that cyber security regulations will replace driving regulations when driverless vehicles take to our roads.

Hacking is one of the main threats to the progress of driverless technology. Elon Musk, CEO of Tesla, has said that his company is implementing layers of security to lower the risk of hacking and to prevent multi-car hacks, but has not yet found a solution.

Andrew Martin, Professor of Systems Security at Oxford University has commented:

‘Nothing is hack-proof – everything is a trade-off between how much you want to invest in protecting it, and how much your adversary wants to invest in breaking it.’

Con #2: Robot ethics

Who would we blame if something went wrong? The driver/passenger? The manufacturer? The software? Would the car try and save the passenger in the risk of a crash, or the pedestrian? How does a computer determine whose life is more important? These are all questions that are currently unanswered.

Con #3: Weather

Bad weather could pose a risk to the responsiveness of driverless cars, as heavy rain could interfere with roof sensors, and snowy roads could disrupt cameras.

Con #4: Driverless cars may take the fun out of driving

Lots of people enjoy driving because of the feeling of being in control, the steering, reacting to the sound of the engine and being alert and aware of your actions. In a driverless car, the car would do all the work for you, so you would just sit there. Whilst that idea will appeal to a lot of people, others may be disheartened.

These blips are likely to take quite a few years to be sorted out, but at the core of it all, driverless technology poses a huge sea change to the way we get around in the future. I don’t know about you, but I think that’s pretty exciting.
