I agree Tesla is far from perfect, just like most everybody else. Their choice of battery location has many sweet advantages, sadly protection from road debris intrusion isn't one of them. The industry has struggled with this going back to the GM Impact/EV1, and why some take a different approach for better protection. My concern has always included first responders, training, etc for the high voltages involved.

I don't believe I've seen series connections of packs be an issue in a damage report. Some even include disconnect features in the connections to reduce the electrical hazard in crash events.
