Starting at the other side of this. What is the human reaction to "side view"
Regular humans have a reaction time of around .250 (1/4 second) but that doesn't include the time it takes to recognize the situation then hit the brake/go pedal etc.
Within that 1/4 second one camera at 36fps would have 9 whole frames to figure out what's going on and react, or 72 frames for all of them.
Add the fact the drivers spend most of their time looking forwards and many seem to need extra prodding to bother looking sideways or backwards.
On the face of it, it would seem the computer would react significantly faster than a human and spot oncoming cars from either direction faster than a human (who can't look in both directions at once)
I can absolutely see further and clearer than the side cameras. Without a doubt. I can also predict better than the software can currently. I can plot what lane oncoming traffic is. I can preposition myself to be successful. You’re overly simplifying complex visuals, thinking, prediction, and maneuvering.
If you think otherwise then let’s bet $1,000 that Tesla will launch either more or higher resolution cameras looking to the side in the next 5 years.
