I think it's the idea of a manual override being lost that people are unhappy about. Even in a fully self driving cars, I think people would express anger at having no way to override the car and steer themselves. I'm a huge proponet of slef driving (if we can get it right) but the driver needs to be able to have ultimate control over the car if wanted. The example here is going to a hospital even if slightly intoxicated and I know Ive heard escaping domestic violence; however, I thik it can be much more mundane than that- what if your car thinks you have a flat tire because a air pressure sensor has gone bad and so simply refuses to move until it reads more than 15 psi or something, despite being full in reality? What if your car sounds like it's about to suffer sudden extreme mechanical failure, but you're a mile from home and don't want to call a tow. The driver should always be able to tell the car the driver's intent. This is a matter of keeping the car useful, secure, safe, and respectful of the basic idea of object ownership. Failure to recognize this and implimenting nanny tech like this will always have the effect of making things less safe and pissing people off. It's just particularly bad when there's not even the benefit of total self driving to accompany it.
