There was no "general agreement" on anything, GS. No one voted. People aired various ideas and opinions on everything, and still do. Telling Gardener that there was a consensus that her idea on a possible electrical malfunction is wrong is "hyperbole" and way too dismissive.
At times, there have been popular opinions, to be sure, and if something was offered that didn't fit the popular idea at the time, the crowd would be dismissive. With so many thinking the car at SWFA was part of the murder, this idea to the contrary was certainly treated like that.
But some of those popular opinions have already turned out to be wrong, such as the idea that her family may have had something to do with the crime, that MB was bludgeoned to death, that there were cameras recording in all 4 corners of the church covering all the halls, and more. But as it turned out, the fact those were the popular ideas at one time didn't make them right - and unpopular (at one time) ideas were better.
Also, the statement that makers have "started designing cars in a way that they wouldn’t malfunction just because a thing called rain happens" overstates the reality -- this is more "hyperbole," as you call it. Cars still can and do malfunction if the wrong thing gets wet, and while it's less common in 2021 (or 2016) than it was 20 or 40 or 60 years ago, it's still possible. It's absolutely possible it could have happened here. The "most likely" idea isn't necessarily the right answer, as you often note.
