The study you mentioned was, even at the time of its publication, quite dubious - finding a negligible correlation (0.23) in amygdalae size in a very non-representative sampling. In a replication attempt that correlation was found to overstate it by more than 3x, finding a correlation of 0.068, which is essentially statistical noise. There's nothing there except clickbait media doing their thing. I'd also add that framing the amygdala as the 'fear center' is itself also quite ridiculous. There also remains the question of identity. I consider myself liberal. I imagine you would object. Who's right? Ah modern 'science', but there I go again challenging that hierarchy.

I'd say a more overt example is playing out on the national stage, where protests in support of (murdered, raped, and starving) Palestinians in Gaza are crushed, because the alternative is to have the executive branch try to extort a $Billion dollars from the host campus, putting universities in peril, to help buy another gold-plated plane or something.
Many cars have something similar (remove SIM card, cut antenna) that allows them to keep working without connectivity
Incidentally, this link recommends termination resistors, which I think are the better answer if there's a suitable connector (which I imagine is the case for most cars). If it's not terminated, I believe it can still pick up a nontrivial signal.

Just look at this https://de.wikipedia.org/wiki/Datei:Wiedtalbrücke_Blickricht...
which is used at 300kph by electric multiple units like the german Inter City Expres.
I've rode over this at about 330kph shortly after opening, it's slightly noticable, but not like a roller-coaster at all, as one might think.
Meanwhile this is also used by more conventional electrical engines for passenger trains up to 250kph, also in 'pusher' mode,
and short freight trains, no longer than 700m, at anything between 160 to 200kph during nights.
According to Wikipedia 'the Bakersfield–Palmdale section of the line will cross Tehachapi Pass, roughly parallelling the Union Pacific Railroad's Mojave Subdivision. Due to its heavy freight traffic and sharp curves (including the famous Tehachapi Loop), there is no current passenger service through the pass. While the proposed high-speed rail alignment will not include any long tunnels comparable to those in Pacheco Pass, it has nine shorter tunnels and several viaducts more than 200 feet (61 m) high. The maximum grade through the pass would be - 2.8 - percent, making it the steepest portion of the Phase 1 route.'
Easy peasy.
Edit: TL;DR? All of this is explained here https://en.wikipedia.org/wiki/Brightline_West
OMG, just join the I-5 after Bakersfield. It's right there. Why are we barreling through the mountains?
