At what point will it become a safety issue if X% of cars in a multi-story garage are electric, considering both the fire-safety of batteries and their weight?



> considering both the fire-safety

Some people may jump on you about the fire-safety of Tesla cars (or BEVs in general), but I want to get ahead of that with a link to the Highway Loss Data Institute's December 2018 report for 2016-2018 motor vehicles, where the Tesla Model X had a RCF (Relative Claim Frequency) of 192, the second-worse score for vehicles in its class, and the Tesla Model S had a RCF of 140, the worst in its class.

Because the report covers model years 2016-2018, the Model 3 wasn't included in the analysis. Regardless, the point about the relative aptitude of Tesla-manufactured BEVs to catch fire in non-crash scenarios is well made by that report.

There's lies, damn lies and statistics.

Yes, Model X (at 192) is second highest in its class.

It's also better than any passenger car in top 10 (lowest at 204) and better than any pickup truck in top 10 (lowest at 205).

So if we care about fire safety, we should replace every passenger car and pick up with the "terrible" Model X.

Also worth noting that, to my knowledge, there wasn't a single non-crash fire in Model 3, which points to a dramatic improvement in battery safety from Model S/X to Model 3, even from the baseline of "much better than most passenger cars and pick up trucks".


> Also worth noting that, to my knowledge, there wasn't a single non-crash fire in Model 3

Before the HLDI report came out, were you aware that there were 20 insurance claims for non-crash fires between the Model S and the Model X over 2 years of time?

Not everybody goes running to social media when their car catches on fire. Perhaps we should wait until the next HLDI report comes out for 2019-2020 before we make presumptions about how often the Model 3 catches fire.


Ok but what happens if the car parked next to the tesla catches fire?


At what point will it become a safety issue if X% of cars in a multi-story garage contain explosive liquids, considering the fire-safety of gasoline and oil, and it's likelihood to leak?


Never, because ICE cars are also fire hazards and all garages must be designed to accommodate that.
