It's that kind of attitude that turns drivers into grease spots.
I can't believe you've never unexpectedly come upon something on the pavement that fell off a truck, that you've never had a deer or a dog run out in front of you, or that you've never blown a tire while driving.
Your statement is 40 ways from foolish. I hope it never takes a fatality for you to learn why.
No you might think this is what happens but you are wrong. Removing speed limits and signs has been shown to reduce accidents in Montana and certain areas of Europe. In fact, I believe there was a city in Europe that removed all safety signs including things like stop signs and there were fewer accidents and injuries. I'm not sure we need to go that far but it has been shown.
