It should of course not run into anything, but it does need to be able to identify obstacles at the very least for crash priority when crazy shit inevitably happens. For instance, maybe it hits a nice squishy Pomeranian that won’t cause any damage to itself instead of swerving to avoid it and possibly totalling itself by hitting a fire hydrant.
Or maybe it hits the fire hydrant instead of a toddler.
At any rate, being able to identify an obstacle and react to unexpected orientations of those obstacles is something I think a human driver does pretty well most of the time. Autonomous cars are irresponsible and frankly I can’t believe they’re legal to operate.
