The risks involved in an ETL procedure aren’t mechanical, but personal. You had to know who to trust with the data you were expunging. As an illegal process, it is grounds for liquidation. If your mechanic was in a tight spot, they could sell you out for a bounty. The procedure starts with the mechanic extracting any sensor data you wouldn’t want subpoenaed, then cleaning it enough to provide an adequate alibi, or else scrubbing it entirely.
