When my daughters took driver's ed in HS about 10 years ago, they informed me that car class no longer included any time on the interstate. The only experience with limited access highways they got was on the simulator. I made sure they got plenty of seat time on the hiway with me as co-pilot before they got their license.
Not sure if that was just NYS or is happening around the country....kids are not learning basic stuff like stay to the right when you are not passing. They also used to teach speed control...pick a speed and stay on it. That means giving it gas going up the hill and letting off coming down. One of the most frustrating things, especially when towing, is pulling out to pass someone and having them speed up when they see you are trying to pass.
I think 90% of aggressive driving is caused by frustration with people that never learned basic road etiquette. Car technology may have changed but urban infrastructure has not....some interstates have short on/off ramps and sharp curves along with heavy traffic.
