It’s not about the cars, unfortunately. The user noticed a specific line of attack that the community was vulnerable to and exploited it.

It’s not an actually reasonable position. It sounds emotionally like a belief someone could hold, which is what made it so effective, but the logic of their replies is what gives them away. They are not actually making reasoned, rational arguments about how this could be done, nor are they fairly addressing their critics.

If not inoculated against this behavior by learning how to specifically not engage with trolling behavior, this community is doomed to lose to it eventually. The trolls always win once you let them in. They enjoy this process and find it a pleasurable recreational activity, even though nobody else does.
