That kind of lane marking (or lack thereof) seems very unsafe. I realize that often this is due to construction / etc but the immediately-to-the-left lane's marker was Very Clear, and didn't have a visible split in it. I had to watch it a second time to make sure that I didn't miss the indications that the lane was splitting away (other than the highway signs). This kind of thing (lack of clear markings) can be really dangerous when driving at night in the raid (road is more reflective than normal), or in an unfamiliar area. The autopilot could be better, but the road engineers should have made sure the lines were painted correctly.

“The autopilot could be better” The car would’ve been destroyed and the driver injured. In this case, autopilot should’ve not just been better it should’ve actually worked. It didn’t even stop the car.

For whatever reason -- a trick of light, snowplows tore it up this winter, who knows. That kind of thing is going to happen and autonomous cars need to deal with it in order to be actually autonomous.

  I believe it's this intersection, judging by the signs in the beginning of video. Paint is not great. https://goo.gl/maps/V9qnLYTL2tn https://goo.gl/maps/V9qnLYTL2tn

  In the UK there would be about three times as many chevrons and they would be much thicker - see figure 4-18: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/223667/traffic-signs-manual-chapter-05.pdf https://www.gov.uk/government/uploads/system/uploads/attachm...

  On a tangible subject: Why do so many US highways use such a light gray colored asphalt mixture? This certainly doesn't help on the contrast with the road markings.
