The IMEI number on the phone is essentially locked to the device, swapping sims won't change it. So a phone activated under your real name on one network could technically get traced back to you even when using a different SIM card.
Also, carrying a phone with both SIMs active is completely unprotected from correlation attacks by anyone with access to the cell tower data. It'd be blatantly obvious that the location of one SIM is the same as the other all the time.
All depends on the threat level you expect, but if you're worried about a VOIP account being compromised to get your real number, you are talking about pretty sophisticated actors.
Yeah I think they would have had to slow down or stop sales and make a big deal about reworking their production lines for better QC. Then come back a year or two later with actual improvements. I think Tesla probably have enough brand recognition that they can survive without Musk so hopefully they kick him out.
I think the US car industry as a whole is due for a major price adjustment, so I kind of see that as it's own issue. Car prices need to be cut at least in half to make them practical as utility items. We're being asked to drive vehicles that costs as much as a house did 30 years ago, and are approaching the same size, on the highway and leave them parked inches from each other.
