Projecting a bit?
It's not clear to me that they meant to cross the border. You seem either unwilling or unable to explain how you came to this conclusion.
The mere fact that you slap adjectives like "clear" and "obvious" on your assertion doesn't magically justify the claims you're making.
The border markers you mention are far apart and don't obviously denote the border unless you already know what they are or get up close to them. At night from a car driving by, they'd be virtually useless... and I can't even see any in the video. Can you?
I'm in southwestern Ontario. Our rural frontage roads tend to have at least a
fence between the frontage road and the main road.
In any case, I brought up frontage roads because you seemed bewildered at the idea that two roads running in parallel close together could be anything other than an international border. Frontage roads are one example, but there are others.
BTW: you do realize that "anyone who lives
in the US and drives" doesn't describe visitors from the UK, right?
Overall, the area where they crossed has a funky arrangement that doesn't exactly scream "international border" except to people familiar with the area, but visitors from overseas can't be expected to be familiar with the area.
Oh, if they were reacting to the animal, then it would have been a complete over-reaction.
Even if they didn't realize where the border was, driving through the ditch was foolish and kinda ridiculous. I'm not trying to suggest that their actions were wise or appropriate.
Still, "unwise and inappropriate" is not the same as "deliberately crossing a border illegally."
CBP, not CBT.
What do you think I claimed?
