I actually think the 50+ are dangerous where I live they all own big cars and think they own the road!
Its like a 3/4 life crisis they go through where anyone under the age of 25 should be behind them or when they pull out on you its your fault for not seeing him pull out on you

Its more attitude towards me I find frustrating not the age!
I'm happy to drive exactly 29MPH because the old gal in front can only feel safe sticking to speed limits.
TBH my feelings change when I see who is driving for instance if an old person is driving and made a mistake should I honk my horn and shout abuse? I've seen this as counter productive as they get more scared.
Does it mean they should be on the road even now, proberly not!
I've seen much older drivers, drive better than 17yr olds even today.
My father has stopped driving, due to my bank telling to stop paying off his minor fracuses as he used to called them

Funny thing about driving, you could be the best driver on the planet. But when you loose control, you loose control period big time!
