從「Tesla said it didn't have key data in a fatal crash, then a hacker found it (washingtonpost.com)」這則裡看到的，原文有 paywall，在「Tesla said it didn’t have key data in a fatal crash. Then a hacker found it.」這邊可以看到全文。

2019 年的車禍 Tesla 說他們沒有車禍當時的資料：

Years after a Tesla driver using Autopilot plowed into a young Florida couple in 2019, crucial electronic data detailing how the fatal wreck unfolded was missing. The information was key for a wrongful death case the survivor and the victim’s family were building against Tesla, but the company said it didn’t have the data.

但後來被發現這是刻意「unlink」的：

Immediately after the wreck at 9:14 p.m. on April 25, 2019, the crucial data detailing how it unfolded was automatically uploaded to the company’s servers and stored in a vast central database, according to court documents. Tesla’s headquarters soon sent an automated message back to the car confirming that it had received the collision snapshot.

Moments later, court records show, the data was just as automatically “unlinked” from the 2019 Tesla Model S at the scene, meaning the local copy was marked for deletion, a standard practice for Teslas in such incidents, according to court testimony.

文章後面的描述比較清楚：在 Tesla 車輛偵測車禍後，相關的資料會馬上被上傳到 Tesla，然後 Tesla 的中央系統會通知車輛本身刪除車輛上面的記錄 (也就是上面提到的 unlink)：

Inside a Starbucks near the Miami airport, the plaintiffs’ attorneys watched as greentheonly fired up his ThinkPad computer and plugged in a flash drive containing a forensic copy of the Autopilot unit’s contents. Within minutes, he found key data that was marked for deletion — along with confirmation that Tesla had received the collision snapshot within moments of the crash — proving the critical information should have actually been accessible all along.

提告的家屬找外部人士從取得的資料中恢復了資料後，Tesla 改口說他們的伺服器上有資料：

Then a self-described hacker, enlisted by the plaintiffs to decode the contents of a chip they recovered from the vehicle, found it while sipping a Venti-size hot chocolate at a South Florida Starbucks. Tesla later said in court that it had the data on its own servers all along.
