If anyone is wondering why people are discussing this particular exit so much, look at this image:
https://goo.gl/maps/Q2Qm5RR3myMkdsFE8See that lane on the right that has solid white lines on each side of it? Now pan around: https://goo.gl/maps/TunvNLGvX9sUTbXp9 It actually leads directly to a barrier. If instead of putting smooth pavement before that barrier, Caltrans had placed grass or dirt or rumble strips or pretty much anything else, this would be a non-issue. But they didn't, so people hit it all the time. You can look at the street view history:
Feb 2008, the barrier is surrounded by cones (probably recently replaced): https://goo.gl/maps/faxMWWBCwXxnqqKS8
Nov 2008, no more cones: https://goo.gl/maps/LPLkCeqeojEgHV679
Feb 2011, the barrier is twisted metal covered in warning signs:

Sep 2011, the barrier has been repaired: https://goo.gl/maps/zs7WrXgUa8cxShKN6
Dec 2013, the barrier has been replaced. Note that this is now a reusable crash barrier. Most crashes won't be noticeable on street view history because the barrier is typically reset within a few days of a crash: https://goo.gl/maps/34oVqmDAJuTepUT76
Aug 2014, damaged again. Now the barrier is shorter (needs to be reset by Caltrans): https://goo.gl/maps/LYHidVpVgCt8uDa48
Oct 2014, now it's reset: https://goo.gl/maps/5uhK8bx8cExJR13z5
Sep 2015, damaged again. Now it's ridiculously short (needs to be reset by Caltrans):

Oct 2015, barrier destroyed again: https://goo.gl/maps/6A6GCESsvjkKGK7A6
Apr 2016, replaced. Now the concrete behind the metal barrier is damaged: https://goo.gl/maps/zUiJzbrDMoUWaJqb9
At some point between 2017 and 2019, Caltrans painted between the lanes to make it more obvious: https://goo.gl/maps/zR8sGB2LxG1dUBSz5
Again, since late 2013 the barrier been reusable. Only particularly devastating crashes will damage it enough to require replacement. Usually Caltrans resets the barrier after a few days. Sometimes it takes them longer, such as when they didn't reset the barrier before the 2018 crash that killed an Apple engineer driving a Tesla with autopilot enabled.[1]
