There are a few reasons why the analysis presented in the article is meaningless:
1 - Without knowing the age distribution of all drivers it's pointless to look at the age distribution of the drivers who had accidents. The age distribution could just be the same as the age distribution of all drivers.
2 - The same applies to the situations where accidents occurred. Without a comparison with data on all accidents you can't infer anything. The pie chart in the article could just be the same for accidents with other brands.
