Appreciate hindsight is 20/20 but:<p>(Hard to judge from dashcam) but car seems to be going fairly quickly for the conditions. Low light, low viz, curving road... and surely the moment you see flashing lights up ahead (ie from the very start of the posted video!) you take your foot off the gas and reduce speed?<p>Don't see much situational awareness on display, either from the car's autopilot or the human behind the wheel. Strategy of blindly following the road at constant speed, hoping it will work.<p>Oh, and how did the (human) driver get so close to the crossing before taking any kind of action? If they'd hit the brakes even a few seconds earlier there would have been no need to steer off the road.
