Valid point, old people tend to drive slower, be less visually acute, less aware of their surroundings. Poor drivers no doubt.
"The relationship between age and driving behavior has interested highway safety researchers and administrators for many years. It is generally acknowledged that the greatest risk of traffic crashes is among teenage drivers. Traffic crashes are the leading cause of death for teenagers across the United States. For both men and women, drivers aged 16 to 19 years of age have the highest average annual crash and traffic violation rates of any other age group." (

BTW, would those "Old People" you are telling to "Fuck off" include your grandparents?
Just thinking out loud.
