All it takes is one incident to make the system unntrustworthy. This is worse because it's an incident in the home. Where your family could wake up or maybe not even wake up because of a piowersocket failure due to a long use to charge the batteries.
You are assuming this is the only incident.Well, it just happened to be on the wall socket that the TSLA was plugged into. All TSLA owners should be warned and TSLA should make an honest effort to make sure all present and future owners are aware this might happen.
