Tesla frequently loses telemetry in serious and fatal crashes [1]. For a specific example you can see here [2] listed as 13781-3074 where the fatal crash was detected by a complaint rather than telemetry. Of reported conclusively fatal accidents, only ~45% were detected by telemetry. From that alone, we can conclude that their telemetry is bad at fatal crash detection. However, when we contrast it against their regular crash reporting where ~90% are telemetry, we can further conclude that either crashes are massively under-reported or fatal accidents are uniquely under-reported (even ignoring the unknown base rate vs reported rate problem). In either case, the massive unexplained discrepancy in the most visible, fatal crashes demonstrates that their data collection procedures are grossly inadequate to conclude any positive safety statistic. The fact that Tesla repeatedly markets safety statistics based on grossly inadequate data collection procedures without any attempts to identify the true, higher rate, and without qualification is criminally repugnant.
