Drivers can judge safe speeds all by themselves. You see, cars come off the roads when you go around curves too fast. So, the way speed limits are established on new roads is to observe the traffic speed before limits are posted, then make signs that are 10 MPH below those natural speeds. Those signs are posted. This is policy withing DOT offices. It is also why motorists generally must go 10 MPH over the speed limit before they are ticketed.
When an accident occurs, the speed limit is used to prevent the DOT or the local government from having liability. After all, the driver was "speeding". It never was about safety.
it’s hard to explain things to people with a broom handle stuck up their ass ...
Could care less about what other drivers do on the highway. Have seen their wrecks scattered all over the country. Have seen hundreds of them pulled over conversing with the local law enforcement officials. I choose to follow the traffic laws. You don’t have to, it’s your business, your choice.
