Honestly, as long as you can just coast across, you’ll be fine. The people who get into trouble are the ones who intentionally stop (like maybe a red light across the tracks) and then can’t start again. Even with the giant “do not stop on tracks” signs, people are just stupid and park across them anyways.
So just make sure you stop before the tracks, or that you have enough speed to get clear of them. There shouldn’t ever really be a scenario where you’re forced to actually stop on the tracks.
I have similar feelings about my partner. They’re constantly in and out of the doctor’s office for a variety of medical issues. It would be nice if there were at least some sort of diagnosis. Like we have family and friends say “oh it’s good that the tests for all of those things came back negative” like it somehow means her symptoms will stop since she wasn’t diagnosed. Every time I hear it, the voice in the back of my head goes “how is not knowing the best case scenario?” At least if you have a diagnosis, you can work on treating the root cause.
