[SystemSafety] What Tesla says about its autopilot

This was in late 2004, so before ISO 26262 - AFAI recall ???

Never did see the vehicle manufacturer's original requirements and 
simply took it that the s/w  process was to meet all 61508 requirements 
for SIL4.

I think that the vehicle manufacturer already had a hardware 
implementation of the device but put out an open tender to see whether 
anyone could do it cheaper. AFAI am aware, they asked for SIL4 because 
of distrust of software relative to hardware.

Otherwise, there was every little evidence of clear thinking anywhere on 
that project.
