Topics:

• There is a new class action lawsuit against Tesla over their range claims.
• The lawsuit alleges that Tesla "marketed its electric vehicles as having a grossly overvalued range in an effort to increase sales to consumers."
• The lawsuit was filed with the U.S. District Court for the Northern District of California. In it, Tesla faces charges of fraud and breach of warranty, among others.

• The fact is, EV range claims are estimates, NOT guarantees.
• Those estimates are for optimal environmental conditions and optimal driving styles.
• For example, if you are driving in winter conditions (environmental conditions), or you are heavy on your acceleration (driving style), then that those will reduce the battery range.
• All car OEMs make similar estimates.
• In general, all engineering estimates tend to be inaccurate.
• Estimates are not contracts, they are estimates based upon optimistic assumptions and conditions.
• If Tesla loses their case on battery range estimates, the net result will be car OEMs will no longer give estimates.
• Previously, I done a whole podcast episode on why engineering estimates are unreliable: https://techleader.pro/a/576-Tech-Leader-Pro-podcast-20,-Project-estimates-are-unreliable
• In that episode, I gave my arguments why we should reduce our emphasis on producing them, as they are not scientific.
• During my long career if I was sued every time I gave a bad engineering estimate, I'd be bankrupt by now.
• What I am working on this week:
  • Nothing, on holiday!
• Media I am enjoying this week:
  • Foundation season 2.
  • Neuromancer by William Gibson.
