Human beings visual systems are far faster than once per second. Your reference is complete reaction time to both process visual information and decide on an appropriate action and actuate a control surface given a state model of the world. Your brain most certainly processes visual information faster than 17 fps doing novel segmentation and odometry.

Tesla's system is also doing much more than simple segmentation and visual odometry. Tesla's latency around actuating the control surface is quite insignificant (a few ms) so I'd argue it is a fair comparison.

Does it have the object permanence abilities of a six month old baby?

In the "FSD Preview" update that came out around Christmas time, the car now shows a bunch of symbols on the road, and signs (aka stop signs) that it recognizes. They don't flicker at all, even while you're driving and a large truck obscures the car's vision of the sign / stoplight. So they likely have started to enable some form of temporal memory into the system so that it remembers what it has observed in the environment both frame-to-frame and overall.

That hasn't been my experience. The visualization only ever shows what I can see with my own eyes, and the cameras are in a very similar position. I've definitely watched traffic signals come and go, all while not moving an inch.
