The first time I used it I was uncomfortable, especially at four-way stops, but the car earned my trust pretty quickly. It's actually about 7x safer than a human driver at this point. It sees everything going on around vehicle and can respond in milliseconds. During our time here it's slowed down to let a coyote cross the road, slows down for speed bumps, even pulls over for emergency vehicles. It still occasionally makes mistakes though, which is frustrating because it works so well 99% of the time. I just don't know how it can perform so well most of the time but then still make these mistakes.
