In this little town of 2800 people we have aggressive, rude drivers of every age.   As for older drivers being particularly dangerous we have had several involved in near fatal accidents. Before those accidents those drivers had been involved in minor scrapes and had amply demostrated they should no longer be behind a wheel. I have a very close friend who suceeded in persuading his father to give up driving.   Some accidents involving older drivers could be avoided and are avoided by the driver or close family members reading the signs and realizing that a person should not be at the wheel of a motor vehicle.   The same could be said of younger drivers.
