Firstly, driverless cars can effectively reduce carbon dioxide emission, through use of alternate source of power.

According to the United States Department of Transportation, congestion costs “US$11 billion” (2015), this leads to emission of “2.4million” pound of carbon dioxide each second and “38.2 billion” tons annually. According to Stern (2008), “almost 40% of total US carbon dioxide emissions are associated with residences and cars, so changing patterns of urban development and transportation can significantly impact emissions.”(1) The Department of transport San Francisco reveals from their research (2017) that, fuel consumption will fall by 12.4 per cent on urban roads by the effective use of driverless cars.

(2) Some experts might believe that driverless cars can be fuel efficient but, experts from the University of Leeds, Bloomberg?argues?that power consumption of autonomous vehicles will drop significantly over the long term but the fuel consumption would not drop but remain the same (2016). (3). We can also see Ford’s “$1 billion” investment in an artificial-intelligence company this year, which concluded that driverless cars could save a certain amount of fuel on low degree of consumption but cannot save fuel consumption considerably as we might expect, and increase the traffic congestion and increase our time in highways and motorways (The Wall Street Journal, 2015) (4). However, driverless cars can not only reduce fuel efficiency but they can also effectively reduce greenhouse gases.

(Lemar, 2015) There is an annual increase of “249” percent increase of emission of greenhouse gases (Kakali Sikdar, 2013) which can be reduced by “2” percent in long run and “1.8” per cent in short run. (5) “Automated vehicles open up opportunities for saving fuel, reducing greenhouse gases emission and saves the environment as well,” U.S. Transportation Secretary. (Anthony Foxx, 2016).

(6) Secondly, the primary concern with transportation is safety; hence the most obvious and largest benefit to the replacement of regular human drivers cars with self-driving cars is the decrease in traffic collisions. According to Lt Gen Dahi Khalfan Commander in chief of the Dubai Police, 90% of the road accidents are related to bad driving behaviour, driving recklessly and speeding under the influence of alcohol, changing lanes without signalling and passing through red lights (Olarte, 2011). The majority of car crashes are caused by human errors, and if this proposition is implemented, the number of fatalities due to car accidents per year will dramatically plummet. In 2012, a Google driverless car had driven over 300,000 miles, with only two accidents being reported, both of which had been a human’s fault (Urmson, 2012).

Autonomous cars will have quicker reflexes than humans which make more reliable judgements and will not commit silly mistakes such as texting whilst driving. As a collateral for reducing accidents, this innovation could theoretically also save the government trillions of dollars each year.

Firstly, to understand how addiction works we have to know what addiction is. Addiction is an intense craving for something, you lose control over its use and continue to use and abuse the substance even though there are consequences.
Hundreds of years ago, the general attitude towards alcohol was that people drank it because they wanted to, not that there was an internal or external necessity. But as people started to realise that there was an irresistible urge towards alcohol and drugs, the concept of addiction came about.
The original belief on addiction, was that the substances being consumed have addictive properties… Blaming the addiction on the contents of the substance. Later the idea changed and (addiction was believed that addiction is part of the addicts character.)
Depending on substances like alcohol and drugs was seen as a (personality flaw.) But later it became clear that addiction is something that a person suffers from, like a sickness or a disease.

Drugs that are addictive, create a shortcut to the brain’s reward system. How? It floods the nucleus accumbens with dopamine (dopamine functions as a neurotransmitter. It is responsible for the feelings of reward and pleasure.) The hippocampus remembers this feeling of quick pleasure and satisfaction, and the amygdala makes a certain response to this reaction or event. All substances of abuse send a strong current of dopamine to the nucleus accumbens.

5. Additional research on phone addiction:
Nomophobia is the irrational fear of losing contact in the world of social media, without your cell phone. If you have nomophobia it means that you are constantly being afraid of having a low battery power, losing signal, running out of airtime, or losing your phone altogether. People often become addicted to their phone because they are insecure, they have no or little self control, they get bored easily or because they have no hobbies to keep them busy. Most people with nomophobia will go to any length to protect their phone, they will always have it near them and will constantly check it for messages or to see how their battery life is doing. The usage of a phone when you are addicted can easily get in the way of your friendships, school work or office work. It is so much easier for a person to scroll through Instagram or to WhatsApp people than to rather work and focus on the job at hand. The word nomophobia is broken down to no-mo(bile phone)-phobia.

Therefore, your head is always connected to your desktop computer. Walking with it makes people feel uncomfortable and the scope of action is also limitedDevice latency is still a problem. It has been significantly improved, but some people still feel sick, especially in some fast-moving scenes or seeing disgusting scenes. This makes people feel dizzy and vomiting.

The weight of the device is also part of the limitation. The lighter the device, the less you feel about it. The better you experience VR, the more realistic it is.The shape of the device is also very important. The way to wear is simple and safe. It is difficult for people like Muslims to enjoy the real feelings brought by the equipment.
