Welcome to the 21st century. Times have changed. Driving robots are now a reality. Adaptive cruise is a real thing, and the most well-known adaptive cruise systems slow down to adjust to traffic speeds, not speed up and pass.

In fact, the most well known system made an adjustment some time ago that it would no longer exceed the legal speed limit.

> rational drivers must presume that the other vehicles on the road may possibly behave irrationally, and therefore must introduce a safety margin for the incorrect behavior of other drivers in addition to the margin defined by their own capabilities.

Exactly. So slow down. Join the train of cars instead of trying to pass them. Maintain a safe distance and don't worry that you will be late. You won't. 20 cars driving 70mph is better than 10 cars driving 80, one driving 85, five driving 75, two driving 90, and two driving 70. It is better for all of those cars, not just the two driving 70. They will all be safer, and they will all arrive at their destinations within 60 seconds of when they would have.

Humans are not machines, of course. But they can work on one important attribute with which every automated vehicle should be programmed: patience. In a world where human drivers increasingly share the road with robots, human patience must adapt.
