(Press-News.org) Second-hand electric cars may be close to a “tipping point” where they become more popular than equivalent petrol and diesel cars in the UK, new research shows.
Researchers analysed data from car sales website Auto Trader, comparing daily views of adverts for electric vehicles (EVs) with petrol/diesel cars.
Interest in second-hand EVs grew rapidly, doubling from 3.5% of advert views in 2022 to 7% in 2023.
Importantly, interest in EVs became more “sticky”. Events such as petrol price increases drove extra EV views – and over time these spikes of attention lasted longer and longer.
“To identify a possible tipping point, we look for evidence that the status quo may be losing resilience – becoming unstable,” explained Dr Chris Boulton, from Exeter’s Global Systems Institute.
“For example, in the Amazon rainforest we examined daily vegetation changes and found the forest is recovering more slowly from disturbances like droughts – making it vulnerable to a tipping point.
“In the case of second-hand EVs, we analysed data from 2018-23.
“Early in that period, spikes in EV interest subsided quickly, in just a few days. Later spikes lasted longer, up to several weeks.
“And over time, EVs made up a larger and larger proportion of the ‘baseline’ state.
“This is a strong signal that UK drivers are becoming more receptive to second-hand EVs – and this will probably increase further as technology continues to improve, prices continue to fall and more EVs reach the second-hand market.”
Professor Tim Lenton, also from the University of Exeter, said: “Our findings provide a clear signal that the status quo – dominance of petrol and diesel cars – is becoming less stable.
“This is an early opportunity signal to the government and to investors to drive change, knowing that they will get a disproportionate return on their efforts.
“Now we know this tipping point may be happening, actions can be taken to accelerate it – helping to cut the 13% of the UK’s greenhouse gas emissions that come from cars.”
Policies to support this tipping point could include more EV charging points (including on-street charging in residential areas), simpler charging services, and improving the electricity grid.
Dr Boulton added: “We’re grateful to Auto Trader for giving us access to this data, which offered a powerful way to assess changing levels of interest in second-hand EVs over time.”
In the new car market, EVs are on course to overtake petrol and diesel sales globally. In the UK, EVs made up just 0.7% of new car sales in 2019. In 2023, this figure had risen to 16.5%.
The paper, published in the journal Earth System Dynamics, is entitled: “Early opportunity signals of a tipping point in the UK’s second-hand electric vehicle market.”

A new name for one of the world's rarest rhinoceroses
2025-03-12
A new study revealed significant differences in the appearance and behaviour of the two one-horned Asiatic rhinoceros species, challenging long-standing classifications and supporting a re-evaluation of their status.
The study, led by zoologist Francesco Nardelli and paleontologist Kurt Heißig, highlights how millions of years of evolutionary pressures have shaped the distinct adaptations of the Indian (Rhinoceros unicornis) and Sundaic (Rhinoceros sondaicus) rhinoceroses. The critically endangered Sundaic rhinoceros has a slender skull, a broader and lower back of the head, and a shorter nose and teeth suited for browsing leaves. In contrast, the ...
Why do children use loopholes? New research explains the development of intentional misunderstandings in children
2025-03-12
Most people are familiar with loopholes. When your boss, landlord, partner, customer, or government asks you to do something you don’t want to do, and yet you can’t say “no,” you may resort to malicious compliance – doing what someone asked, but not actually what they meant. Most parents are probably familiar with such “little lawyer” behavior too: if a parent says, “Time to put the tablet down,” a child might physically put the tablet down on the table – and then keep playing on it. While such ...
How satisfied are you with your mattress? New research survey aims to find out
2025-03-12
Sleep quality is a crucial aspect of health, yet while adults spend around a third of their lives sleeping, there is surprisingly little research on mattresses. Mass General Brigham researchers developed and tested the Boston Mattress Satisfaction Questionnaire (BMSQ), a new tool to rigorously assess mattress satisfaction and characteristics.
They administered the BMSQ to a representative sample of over 1,000 adults in the United States, finding that the tool is internally consistent and viable for assessing mattress ...
Democracy first? Economic model begs to differ
2025-03-12
Recent studies on economic growth report that preventing the abuse of state power through democratic institutions is critical to a nation’s development. However, there has been little prior research on how societies transition in response to the two conflicting goals of limiting the state’s stranglehold on governance while improving its administrative capacity through citizens’ political participation.
Osaka Metropolitan University Associate Professor Ryosuke Okazawa of the Graduate School of Economics led a team that ...
Opening a new chapter in 3D microprinting with the dream material 'MXene'!

The Smart 3D Printing Research Team at KERI, led by Dr. Seol Seung-kwon, has developed the world’s first technology for printing high-resolution 3D microstructures using 'MXene,' a material known as the dream material.
MXene, first discovered in the United States in 2011, is a two-dimensional nanomaterial composed of alternating metal and carbon layers. MXene possesses high electrical conductivity and electromagnetic shielding capabilities. Due to its easy combination with various metal chemicals, MXene has gained significant attention ...
Temperature during development influences connectivity between neurons and behavior in fruit flies
2025-03-12
The rate of development of poikilothermic animals, such as insects, fish, and reptiles, is determined by environmental temperature. A research team at Johannes Gutenberg University Mainz (JGU) has recently demonstrated how temperature can affect brain development in fruit flies. "In the area of the brain we examined, neurons formed more synapses and connected to more synaptic partners at lower temperatures," stated Dr. Carlotta Martelli, head of the team at the Institute of Developmental Biology and Neurobiology of JGU. In their study, the scientists focused on the olfactory circuit of Drosophila melanogaster, because the sense of smell determines important behavioral patterns in ...
Are you just tired or are you menopause tired?
2025-03-12
CLEVELAND, Ohio (March 12, 2025)—Multiple menopause symptoms can make women feel fatigued. Hot flashes, sleep problems, pain, and depression are just a few. A new study suggests that heavy or prolonged menstrual bleeding may increase fatigue, which helps to explain why midlife women are two-to-four times more likely to experience debilitating forms of syndromic fatigue. Results of the study are published online today in Menopause, the journal of The Menopause Society.
Most women transitioning through ...
Fluorescent dope
2025-03-12
Kyoto, Japan -- We're all familiar with Pavlovian conditioning, in which a reward-anticipatory behavior follows a reward-predicting stimulus. Perhaps you experience it yourself when passing a café or restaurant and catching a whiff of something delectable.
Behind this mechanism is dopamine released within the striatum, the largest structure of the subcortical basal ganglia, which links motor movements and motivation. Yet it has remained unclear exactly what kind of dopamine signal is transmitted to the striatum to cause this behavior in primates.
In order to understand this dopamine signal, a team of researchers from Kyoto University ...
Meningococcal vaccine found to be safe and effective for infants in sub-Saharan Africa
2025-03-12
University of Maryland School of Medicine (UMSOM) researchers helped conduct an important new global health study that found a vaccine that protects against five strains of meningitis prevalent in sub-Saharan Africa is safe and effective for use in young children beginning at 9 months of age. This study provided evidence that formed the basis for the World Health Organization’s (WHO) decision last year to recommend the pentavalent Men5CV meningitis vaccine for infants ages 9 months and older.
Results of the study were published today in the journal Lancet.
In January 2024, the WHO recommended that all countries in the African meningitis belt introduce Men5CV into their routine immunization ...
Integrating stopping smoking support into talking therapies helps more people quit – new study
2025-03-12
Research from the University of Bath, funded by Cancer Research UK, published on No Smoking Day 2025, shows that integrating smoking cessation support into NHS Talking Therapies for depression and anxiety increases quit rates. This is an important step in addressing the high rates of smoking in this population.
Led by Dr Gemma Taylor at the University of Bath, alongside researchers from several other institutions, the study published in Addiction also found that adding smoking support to mental health treatment didn’t disrupt therapy. Instead, it offered a practical way to tackle mental and physical health together.
About the Study
The trial was conducted across four NHS ...
