Your research is superficial at best. Don't bother.

It's not mine actually most of it in an Australian context is from Monash University e.g. just for starters:

It has been widely confirmed that young drivers have a greater risk than other drivers of being involved in a traffic crash. The elevated crash risk of young drivers results not from greater distances driven (and thus greater exposure to risk) than other age groups, but from greater risk per unit exposure. A variety of factors may contribute to this high risk level, the most obvious of which is lack of driving experience, since driving skill, like most other skills, is probably acquired largely through practice. Research in Victoria has shown that the rate of casualty crash involvement per distance driven decreases steadily with increasing driving experience. However, experience is not the only correlate of age which may influence crash risk; other factors may be responsible, at least in part, for the decrease in crash rates with increasing age and experience. For example, it has been argued that young people around minimum licensing age are at a stage of life where they reject parental values, strive for independence, experiment with roles and become heavily influenced by their peer group and its values. Thus young people may be motivated to drive fast or take other risks in order to test their own abilities, to demonstrate independence from authority or to impress their peers.

Although driver age and experience are highly correlated, it has been seen as important to determine which is the better predictor of crash risk. The consequences for countermeasure design could be profound. A finding in favour of experience would strongly suggest that the young driver problem is primarily a result of skill deficits, which are gradually overcome with increasing experience of driving. In this case, further research and countermeasure development should concentrate on accelerating the development of those skills which are critical to safe driving. On the other hand, if age is the main predictor of crash risk, countermeasures should focus on age-related motivational and lifestyle factors.

This short report has presented an analysis of risk of crash involvement estimates for 1988 in Metropolitan Melbourne. By necessity, the analysis was age based, in contrast to the original work which was primarily experience based. It was noted that factors other than the ambient level may have affected the incidence of reported crashes, perhaps reducing the direct comparability of the two sets of results. Nevertheless, the same general patterns of results have been obtained, namely the increased risk of crash involvement for younger drivers, the approximate equivalence of risk as a function of driver gender and the elevated risk of night-time driving, particularly after midnight, and for 19 year old drivers.

Monash University Accident Research Centre (MUARC) researcher, Dr Ashleigh Filtness, found that younger male drivers are more susceptible to the effects of sleep restriction than older male drivers.

Put simply, mandatory testing of older drivers isn’t cost effective and is discriminatory. It may seem easy to argue that older people are more likely to have crashes and should, therefore, get off the road. Surely then we would ban all 17 year old males from driving until they are 25?

Not only is there no evidence to support mandatory testing of older drivers there also needs to be recognition that there are real disadvantages associated with age based mandatory assessment. In 2050 almost one in four people will be over 65 and one in ten will be over 80. They will be working, going to the gym, spending money in cafes and restaurants, going to the movies and doing everything they can to stay mobile and active. Driving is key to that and we need to work out ways to help them stay on the road and to drive safely. To do anything else is simply discriminatory and uneconomical.

The death of any Australian on our roads is tragic and the recent spate of young driver deaths on our roads highlights the tragedy, ten-fold. Unfortunately, the death of young Victorian drivers over the past month reflects the over-representation of young drivers in our national road fatality and injury statistics.

More than a quarter of all fatal road injuries and hospitalisations in Australia are in the age group 17 to 25 years despite this group comprising only 15 per cent of licensed drivers. Despite comprehensive Graduated Licensing Systems introduced throughout Australia being initially successful, road fatalities in this age group have remained relatively constant over the past decade, pointing to the urgent need to enhance these systems.

Newly licensed or novice drivers are at increased risk of crashing, especially in the first months of provisional licensing. Early research in Western Australia found 14 per cent of young drivers crashed within the first 12 months of driving and that the risk remains whether the drivers are licensed at 16 years of age (as in many states of the United States) or at age 17 or 18 years as in Australia. The disproportionately high number of newly licensed drivers in the crash statistics has been attributed to factors such as inexperience, an inability to identify hazards, night-time driving, carrying same-age or peer passengers and risky driving behaviors such as speeding.

[In regards to older people and those with dementia] "There is no randomised evidence to indicate whether neuropsychological, on-road or other assessment of driving ability can help support safe drivers remain mobile, or to reduce crashes."

Similar peer reviewed Research from other highly regarded institutions in the UK, North America (e.g. https://www.nhtsa.gov/research) Europe and even the World Health Organisation come to the same conclusions in terms of younger male drivers being the high risk of causing accidents groups and older drivers being much less likely to cause road accidents but much more likely to die if involved in one.
