An insurance company says there is a 77% likelihood that you will be responsible for a car accident in your lifetime. The current US population is about 320 million. a. How many will likely be responsible for a car accident (assuming stats stay the same)? b. What if we removed 100 million people from this risk by having them take public transit/bike/work at home/etc.? Now, how many would be responsible for a car accident? c. There is lots of discussion around self-driving cars. There is some early data that could reduce the risk of accidents by 94%! How many accidents would we expect to still happen if everyone had self-driving cars (and we still had public transit, etc.)?
