It's a matter of risk vs. reward. The reward for self-driving cars is huge. If it screws up once or twice and makes you late, you don't have a whole lot to complain about. From the developer's point of view, it's not all that embarrassing because it's naturally framed in the context of "yeah, but it's a self-driving car." But the situation is totally different with advertising. It's not "I was late because my amazing scifi technology malfunctioned"; it's "I was late because of a crummy commercial". The consumer doesn't get any tangible reward for this, so they're just pissed off. And the developer and advertiser end up embarrassed because they did something shady and it screwed someone's day up.
