"Is it safe to drive 100 Miles an hour in a city?"
"Will I get a ticket when I speed?"
It's a gamble, no one will be able to tell you who will and wont run away with your money.
This is a good way of looking at things.
There are rules and advice stating 65mph zone, but people do it anyways and go over 80mph. Again, its their gamble to hurry not be late a certain location, but the risk is like : 1. Get a ticket 2. Get into a accident and now you are handicap etc or dead.
