Personally, I don’t really feel that scientology is particularly worse than other religions. So you could just say that Trump supporters are more religious than political, really. Though, I don’t think that’s unique to Trump supporters, really - modern politics really is a lot more like a sort of religious thing rather than about the actual policy for a lot of people.

For the same reason that people dangerously exceed speed limits.

I think you might have picked a bad community to share your sympathies for smooth car traffic, I’m afraid.

For what it’s worth, I think it’s reasonable enough to forbid pedestrians from crossing high-speed (60+ mph) roads, but otherwise they should have full right of way over any road, and fuck the cars. They can just be patient and deal with it.
