Karpathy is biased when it comes to self driving. Example: You can't both have humans teleoperating like he claimed, AND have cones disabling Waymos. Waymo's mistakes such as one where they were going around a parking lot honking at each other tells you they don't have humans in the loop except in the most extreme cases. He's likely correct that it's not self driving 100% of the time, but what if it's 99.999% and in the 0.001% the humans have to tell the Waymo how to get out of a very tricky situation?
