Tesla is a great American car company for many reasons.  One of them we should all love, is that the software is written in house.  Most auto makers in America piecemeal cheap foreign software and parts and then try to make it all talk together.  Which is why it still feels like it's from the early 2000's.  I believe Ford's CEO did an interview on this.  When you buy Tesla, you are actually buying American.  @Tesla
