I've done that and it's really hard to get enough of an angle to get your wheels up over those rails to the outside and safety. As demonstrated in the video, all you can do is dump it and try to drag it over the rails.
I had an unpopular opinion lately when somebody I worked with was hit by a train in their car and sued the railroad saying they couldn't see a train approaching an ungated intersection due to excessive foliage along the tracks that blocked their view of it.
To me, bottom line is if you get hit by a train, it's your fault whether the crossing guards are working or not. Even if the gates are up, I always look either way before crossing the tracks and I would say that's the reason tankers and schoolbuses always do the same.
An area in a nearby town has signs at the crossings saying to be cautious because a lot of the locomotives/trains are operated by remote control and there are no humans on board. That's kind of disturbing.....
