I went to meeting a few weeks ago at Eisenhower where the CEO of Voyage talked about the status of the project.

Voyage Self Driving Car-a.pdf - Google Drive)
While they are making progress, they still have a ways to go, for example he talked about how the car was going down one of the roads and got confused by a shadow of a palm tree in the roads.
I think most people feel that they would never get into one of those things until they are 100% safe. Well, my answer to that is they get into cars with drivers that look at their phones, play with the radio, talk to people in the back of the car (looking back as they do). None of that is "safe". Over 39,000 people die in car crashes each year. IF the Voyage could reduce that by a third (or more), then we would save a lot of lives. There are a lot of stupid drivers out there, we can't fix them, but if the car does something the programers didn't expect, then they can correct the code.
