I saw comments about Corolla etc.
In 1994 I went on this hastily built mountain road that connected Sarajevo, which was under siege, to the rest of the world. You needed to go through a tunnel, under the airport that was dug during the siege. The road itself was actually quite good, but besides snipers, anti-aircraft guns shooting at you, making mistakes while driving is fatal. To turn anything longer than a 10-passenger van, you need to get out of the car, lift the rear end, and make it work.
A year after I traveled that road, these guys died when a French armoured vehicle, which was too heavy plus not experienced driver, and plunged down the mountain:

The Black Bear pass is far, FAR worse. And like you said, as you know, the margin to make mistakes is super low. Car with AWD, no 4LO to slow you down etc. I mean, people died there in vehicles built for that. I posted that JEEP plunging from pass, and that is not the worst part of the road. Luckily, the driver recovered from paralysis.
