Final answer:
Drivers aged 70+ and especially 80+ generally have a higher fatality rate per 100,000 drivers compared to younger drivers, due in part to age-related health issues. However, their actual danger on the road can depend on a variety of factors.
Step-by-step explanation:
When looking at the fatalities per 100,000 drivers on the road, research typically shows that drivers aged 70+ and especially 80+ have a higher fatality rate compared to younger drivers. This is partly due to physiological factors such as slower reaction times, poorer vision, and other health-related issues that can affect driving ability in older age groups.
However, the question of whether these drivers are more dangerous is multifaceted and can depend on various factors, including road conditions, driving habits, and vehicular safety. Some studies have found that elderly drivers often take precautionary measures such as avoiding night driving or adverse weather conditions, which can mitigate some risks.
Overall, while the driver fatality rate tends to increase with age, indicating a higher risk for older drivers, it doesn't necessarily mean they are more dangerous to others on the road. Factors like driving less frequently and being cautious can balance the increased personal risk.
