So having a 1000watt stereo impairs driving? Older people with cellphones in their ear is worse than having a loud stereo. The stereo is only a distraction if they're trying to play with it at the time... if it's just playing it won't do much.
I had a 2000watt stereo, didn't impair my driving at all... But it sure didn't warn the Metro Transit Authority City Bus from slamming into the front fender (passenger side) of my car at over 50mph, after running a red light. If anything, my stereo should have warned the bus driver that I was in the intersection...and NOT to run a red light. If I had sped up any sooner and not taken the precaution of slowing down before this intersection, the bus would have completely t-boned me and I wouldn't be here enjoying fine Nissan products with you folks... It's not in the demographic, it's just in the particular driver. Yes we see a lot of young folks, and a lot of old folks driving wrecklessly, however, how often do you see young drivers driving on the wrong side of the road?

Whats left of my last car

 

It was implied it was an elderly driver in the second post of this thread. Acknowledging it could have been a different demographic is hardly holding a grudge toward young drivers. If you want to go by stats, it appears the young do have more incidents.

"Are teens as a group the worst drivers?

Yes, accidents by teen drivers far outweigh their proportion of the driving population, while these individuals represent only five percent of all licensed drivers in the United States. When driver fatality rates are calculated on the basis of estimated annual travel, teen drivers (16 to 19 years old) have a fatality rate that is about four times higher than the fatality rate among drivers 25 through 69 years old."

"The characteristics of young drivers' accidents?

There are significant traits common to younger drivers’ accidents.

44% of crashes involving teenage drivers are single vehicle crashes. Frequently, the car left the road, turned over or struck a tree or pole.

82% of teen car crashes involve driver error -- a much higher rate than any other age group.

Incidents are more likely to occur on a Friday or Saturday evening with multiple teens in the car.

Crashes involving teenagers kill more passengers than those where the operator was older.

Safety Belts and Teens 2003 Report: Teens have the highest fatality rate in motor vehicle crashes than any other age group."

 

I think I saw an NBC Dateline (or similar) program that confirmed what you posted. I personally never had any accidents or incidents with sub 21 y/o so I personally can't confirm this. But I have had numerous incidents with elderly drivers.

Peace.
