Both are from Oct 2025, one in Florida, one in Arizona, both cars were 2020 Model 3's. In both cases FSD was engaged per Tesla's own filings, and the car was stopped dead on the freeway and was struck by a vehicle at freeway speed. In the Arizona case it was 3am, the Elektrek article doesn't seem to have the time for the Florida case. Tesla is currently refusing to share all the data with the government saying they reported what is required the rest is company secret.
the general theory is either both cars "phantom braked" and got hit or more likely in at least the 3am case, the driver either fell asleep o was drunk, FSD software actually has a camera watching the driver and if the driver is not paying attention for a certain length of time, the car shuts off, but it's supposed to pull off the road safely and then shut down and it contacts tesla to let them know it's done so. Part of the info tesla is refusing to hand over is in fact did the car just stop dead on a freeway because the driver was not paying attention and if so did it notify Tesla it had done that.
The article points out it could have been medical events caused the drivers to not pay attention but in any case the appropriate response would be pull safely off the road and then shut down, NOT stop dead in the middle of the freeway and get the driver killed.
