The recent MotorTrend review of the S P85D focused on the incredible performance of the car. However, there was one nugget buried in the story... The reporter mentioned that Elon told him that they are making an average of 20 hardware changes a week to the car. I know nothing about the auto industry but this strikes me as a lot of changes. I take it to mean that they are continually working to improve the car. I assume that most of these changes are small and intended to improve the quality or performance of the cars. I was wondering if anyone knows if this is an unusual number of changes for a car which has been in production for several years or is this routine? It does give me some reassurance as I am waiting for delivery of my car that for every week of "delay" I can expect 20 improvements.
