The worse drivers I've seen are NT's hands down. Either they are
incredibly distracted to the point of being dangerous and inept at the manual/physical functions of driving or they are over aggressive and over confident -- speed, tailgate, drive under the influence, etc. Rules of the road are mostly suggestions.
Seriously, I've seen people drive with their elbows and use the steering wheel as a writing pad to jot notes while using a cel. phone. My overachieving Yalie friend got busted going 100 mph in a 65 zone but she said "it was okay because the highway was straight" and she wanted me to "check your mirrors" to see if any cars were coming behind us so she could drive over 6 lanes to the right turn lane -- from the left turn lane. And we were already at the stop light. I didn't even look and told her 'no'.
Bad drivers are divided into 2 camps.
1) Those that
know they are bad drivers. The honest minority.
2) And those who think everyone
else is a bad driver. These are the truly dangerous folks. And the majority.
As a 'field officer' with a company fleet car and company insurance, I got routine 'good driver' tests and educational materials. They would play horrific live footage of accidents at our regional meetigns right before ending to scare us into driving well on our way home. Most people are
not good drivers. Everyone has bad, even criminal habits.
If you think you are one of the better drivers on the road, it's more than likely that you are not.
This is especially true of you guys out there.
