I guess you chose to completely ignore the part where I said the computer can't process something a sensor didn't detect. For example for the Subaru system, at the farthest reaches of the system, the difference detected between the two cameras may only be 1 pixel. If you decrease the separation distance that will shrink to a subpixel level (1/4.7 to be exact), where there is essentially no difference. You can throw a supercomputer at it and it won't be able to extract information that didn't exist. This is illustrated by the "enhance" parodies that are done:@stopcrazypp "Actually more processing power would not solve the problem. "
The closer the two cameras are together the less diiferentiation so the computer would need to be able to make up the loss.
This is in response to your suggestion that it saves money to go with a stereo camera system and also evaluating what makes sense in a stereo system: a wider housing to increase the separation distance vs two closely spaced sensors with 4.7x-22x the resolution (plus the required increase in processing power, lenses, and sensor size). The latter option would be multiple times more expensive and doesn't make sense from a business perspective (which is why Subaru chose the separation distance).@stopcrazypp "The computer can't process something the sensors didn't detect. Tesla would need to use two higher resolution sensors that is 4.7x the horizontal resolution of Subaru's (given sensors typically increase in both horizontal and vertical resolution at the same time, in practice, that might mean a sensor with 22x the MP). That's going to be very expensive."
Well...we wouldn't want a Tesla to get as expensivel as a Subaru.
Keep in mind the option for Autopilot is only $2.5k (for the Model S, might be cheaper for the 3), plus Tesla is including the hardware in a 35k EV. It is far more useful to just use a mono system plus radar (supplemented by cameras of multiple fields of view) than to invest that money on a stereo system. That seems to be the path Tesla has chosen anyways, so this discussion is kind of moot anyways.
