I think the point is that there isn’t a good enough reason to put internet in a car that negates the risk of it.
It is like adding lead to food. It’s a cheap sweetener with no calories. You can argue that cheap sweeteners aren’t important to you, but I don’t think you can argue that it isn’t a good reason. It just isn’t a good enough reason to negate the risk.
This is a long one, and I want to start by saying that your comment is a super popular belief. Even so, I think misses the mark a little bit.
Everything in the political sphere is emotions based. ‘Murder is bad’ isn’t some ultimate truth. We care about other people and ourselves. That emotion then leads to the reasoning that murder is bad and should be illegal. Same goes for everything else.
What conservatives tend to do is say ‘murder is bad’ and ‘there is a group that I hate’. They then abandon the truth of what murder statistics tell them and blame it on the out group which justifies the second emotion. They’re not wrong because it is emotionally centered (again we all do that). They’re wrong because they aren’t willing to examine that emotional motivation vs reality.
All of that to say that if we think the problem is emotionality we are probably making similar mistakes even if the outcome is better. To paraphrase a very true statement in Futurama - There is no scientific consensus that life is valuable.
