Please note the following:
- This was a freak accident that happened yesterday
- Tesla proactively reported this to NHTSA (which also explains response time as well)
- NHTSA is opening a PRELIMINARY investigation that will pretty much inspect all aspects of the crash
- Again, it was an accidents-- they happen everyday but of course in Tesla fashion this was rather "spectacular"
- The sensors would not have read anything if nothing was there (in this case under a semi that is perpindicular), the timing had to be right-- had it been a few seconds earlier or later- I am confident the driver would have survived but the fact that the initial point of impact was the windshield I hate to say it but head trauma or decapitation were probably cause of death just based on sheer physics.
- If this were any other car the outcome probably would have been the same-- again physics
In a nutshell: Accidents happen. Move along.
