I am sure Tesla car works correctly but Tesla should not portrait itself as righteous arrogant by ignoring the driver in distress.
I can only report on the response Tesla has given me, and the cases I was peripherally involved in and have had a direct working knowledge of.
In each of these cases, Tesla took the incident very seriously and escalated the issue to the proper team for handling the analysis, and where necessary the fix. I would say that the time to respond by an individual in support was quick (within one hour), to escalate to the second level and engineering (24-48 hours), to provide a complete response (7-30 days), and a fix (60 days). Here we were dealing with a collision, and in another case, a failure of AutoSteering.
For accidents, I believe Tesla prioritizes calls to their call center, and the average length of time to get someone on the phone is even shorter.
This individual claims she got no response from Tesla, which on the surface sounds strange. If on the other hand, she meant that she did not get a complete response, that is entirely feasible. Tesla was upfront with us in terms of how long the response would take. Had we not known this upfront, we may have concluded Tesla was not paying (enough) attention.
Once news media or lawyers get involved, there are often immediate constraints placed on the type of language and how the flow of information moves. When dealing with businesses, it is helpful to utilize someone in sales as your advocate (often a district manager, or even head of North American Sales), but with Teslas move to online ordering, who that interface is has become suddenly opaque. Customers are often left scratching their head as to who to escalate to within Tesla - when compared with how quickly news organizations pick up stories, it is easy to see how this happened.
I have been fortunate to have found helpful people at Tesla along my journey, sometimes appearing at just the right moment. These have been like little angels that I've held on to.
In many cases of customer dissatisfaction, the biggest complaint is often lack of communication or poor response time. I've seen response times swell as more customers have gotten their deliveries, and Tesla has attempted to address this by increasing staff to varying degrees of success.
Purely looking at statistics, here in the U.S., there are over 15,000 vehicle accidents per day, resulting in over 90 deaths. Factored together with the number of registered vehicles on the roads (272M) vs. the number of Teslas, we might be able to conclude that there are somewhere between 10-20 accidents per day involving a Tesla. That estimate seems manageable, but I don't know the true numbers are.
In many cases, the crash investigation study is done by a law-enforcement or insurance investigator with some assistance from Tesla or their training partners where needed. The point is, the weight isn't entirely on the manufacturer to respond in these cases, although Tesla might want to consider some additional "white-glove" or hand-holding to prevent stories like these from going critical.
For Tesla, escalating to a customer success manager who can navigate the inside of Tesla and can further escalate where needed might work well. When I have had major issues with a supplier, I would eventually be handed to someone in customer success, whether or not I came through Sales, Engineering, or in one case, a public relations team.
I have on one occasion went to the media on an issue, and the amount of attention was intense and continued for nearly two years (
