Have we seen similar levels of damage in other cars that carry large battery packs and have been in head-on-collisions?

I dont really have any commentary one way or another about autopilot or the safety of batteries, I'm just thinking there are probably other accidents that have happened in the industry in similar conditions to this.

For example, the Prius and Volt have been on the road for quite some time, and both cars carry relatively large batteries (though certainly not as large as that on a Model X). When involved in head-on collisions do they see such drastic damage/fires?

Just curious. I don't know that its even fair to compare those types of vehicles given the difference in the size of battery.

I think the old prius used lead-acid batteries, IE conventional automotive batteries. This significantly reduced the risk of fire, though I don't think that was the main reason for choosing them

No, all Prius prior to model year 2017 used NiMh batteries. Some in 2017 were starting to ship with Li-ion batteries.
