I don't really see that happening at Fremont. Just because the company supplying the stainless steel for the CyberTruck just built a multi-million dollar facility 100 miles away from GigaTexas. If any hint that Fremont would be the location, the new steel plant would definitely not be built in...
I was also concerned about this. Being in Pa, we get some pretty rough snow and ice storms which would cover the cameras quite quickly. Many times I would have to pull over just to clean the headlights just to aid in visibility and safety.
