That’s a far cry from seeing a broad software glitch mysteriously, yet quite plausibly, hit “certain people” trying to get to the polls on election day. Perhaps their self-driving car suddenly can’t quite read the road sensors, you know, just enough where reliability is suspect and these certain people just don’t feel comfortable using their car for that day or that week.
You’re right, stuff like that would never happen.
It would certainly raise a scandal, though if we are going to be tinfoil about it, a system that deals poorly with a large pedestrian presence would be one that might deal poorly with Election Day. After all, these things do have to park unless a competent driver is on board to do that, or if it will just leave off the passenger then come back later.
