Surely if I were a bad driver I'd have been caught by now? Or I'd have hit something? I mean I don't avoid the police, I don't own a radar detector, I don't drive differently when I think nobody is watching. You're welcome to ride with me if you want a demonstration. I watch where I'm going, I never play with my phone, eat, or do other non-driving things while I'm behind the wheel. I do all my own mechanical work so I have a solid understanding of how the car works, I have a good understanding of physics, I have excellent vision and good situational awareness. I obey the laws generally and am not aggressive. I am absolutely confident that I'm a better than average driver and would challenge anyone observing to point out a deficiency. Around here probably 70% of the population can't even drive a manual gearbox, something I consider a fairly basic measure of competency.
