The probability of encountering something like this is so astronomically low, you'd be better off buying a newer, safer car because you're more likely to be killed driving to the airport to get on a 737 MAX.
It's perfectly rational to decrease the probability of getting involved in such a scenario even if the probability is very low. It all depends on the (subjective) cost of this incremental improvement to OP. In addition there is the benefit of being able to send a signal, and the associated utility is likely non-zero to OP as well.

What if OP already has the newest, safest car?
I see people saying they won't fly on Boeing planes, but I see very few people saying that they are rebooking all of their tickets to fly the last row.
If you are willing to take such actions around the model of plane you fly, do you take similarly drastic actions around other more statistically dangerous risks? Do you wear a helmet in your car? Do you book the last row whenever you fly? Do you take transit instead of driving a car? Do you avoid traveling to countries with elevated traffic risks?
I get the idea of minimizing risks, but picking the model of plane you fly on has such a small marginal effect.
Therefore it's very rational to take great care about your irrational fears and feelings.
