There’s a TV show here in the Uk called “race across the world” and in last season they had to cross the gap. Was really hoping for racing jeeps and armed militia but sadly (and sensibly) they took a boat.
BTW: It was actually Ushuaia to LA, not Canada.
Should have called the series “half way up”
It's commonly done now, and you can totally do it yourself in any vehicle.
If you're smart, don't drive at night and don't go looking for trouble, there's no reason to think you'll have problems.
After driving the Pan-Am I drove right around Africa through 35 countries. Never had a single "bad" moment, never heard a single gunshot. I was in LA a couple of months ago, heard gunshots.
I've driven the entire Baja peninsula many times and done a road trip across much of central Mexico.
