I don't have any personal information on the subject one way or another - I've left a few, and never been contacted about them, but I wasn't really expecting to be contacted.
Your description is distinctly different from the description we were given a couple years ago. Where did you develop this understanding?
I believe @greentheonly on Twitter (@verygreen here on TMC) looked at the code and figured out that when a bug report is captured it isn’t transmitted, just stored. My own experience with a mobile tech appears to verify this as well. They were troubleshooting an audio issue that I and several others were experiencing a year ago and the mobile tech asked me to shoot him an email whenever I created a bug report about the issue. He said that he would then remotely connect to my car and download the recently captured bug report log files. Unless I notified him there was a bug report to look at he would had no way of knowing I submitted a bug report.
