Car porn is getting a whole lot more dangerous, a new study says.

Car-related death rates are up, but it’s also been on a decline for the last decade.

The new study by researchers at the University of Sydney found the rise in car-related deaths is the result of people watching videos they can’t really control, and not the work they do.

Carpentry work was also on the rise, but car-building work fell by 15 per cent over the same period.

“A lot of this increase in car related death has been due to people looking to exploit this opportunity to engage in illicit activities in a dangerous way,” Dr Anne Bannister said.

“This is an area where people are not fully aware of the dangers they’re putting themselves in.”

Car-building and car-painting became more dangerous in 2016, and the number of car-making and carpainting deaths in the study fell from 561 to 521 in just three years.

But car-paintings and carmaking are both illegal in Australia, and car painters are also considered a criminal offence.

“It seems that the people who are making these products in Australia are the ones with the most to gain from these offences,” Dr Bannison said.

The study found that carpainters have been involved in an increase in traffic-related accidents in the past year, which are then blamed on people looking for cheap and fast cars to rent.

The study also found the rate of car accidents involving motorcyclists in Sydney has been increasing for several years.

There were 1,819 motorcyclist deaths recorded in 2016.

While there have been other studies into car-sport, Dr Bunnison said car-themed porn sites have been relatively recent, and have been largely ignored.

“We’ve been seeing a lot of videos that have been uploaded to the internet in recent years, and we don’t know why,” she said.

She said while some people might be interested in watching car porn, the people making it should be aware of what they’re watching.

It is estimated that up to 50 per cent of people who watch car-based pornography in the last year have a pre-existing condition that would make them more vulnerable to the health risks of the product.

Dr Banneston said more than half of the people in the survey had not been told that they could restrict their viewing to only a certain number of people.

She said there are now ways people can protect themselves from exposure to the harmful content.

One of the ways to protect yourself is to ensure you have a strong password.
