Model S total coolant failure

So after 2 runs of ludicrous plus starts (total of 20 seconds) I arrived home with my 2020 P100D with 6k miles to hear the coolant fan roaring. Ok I've heard that before. But then later I see massive amounts of "fluid" running down the driveway and stains on the street and around the corner after taking the car for a short store run. WARNING! Coolant failure! Power reduced!

So this was not a small leak, but a total loss of coolant. What gives on a new 2020?
Don't think OP cares what happened to your (I assumed) BMW. Totally irrelevant.

OP: what'd the SC say?
Don’t you know the protocol? Any thread talking about a model s break down must also contain a post about an ice break down that’s completely irrelevant to the topic.

Warning: someone here recently destroyed their battery pack due to overheating after coolant loss. Not sure if they kept driving for extended time after the coolant leak or what but be cautious
Shouldn't the BMS prevent this from happening by severely limiting the power (maybe 25 to 40 kW) or just shutting the car down?
