I said, "One of the main problems is that often the tracks are raised above the street level enough that some vehicles can get high centered." The limo was an extreme example, but lots of vehicles can get high centered.

If you look at enough of these videos, there are several where they have barricades for both sides of the road, on both sides of the tracks, especially for multi-track crossings, apparently to prevent people from driving around them or creeping over the supposedly vacant track and getting clobbered anyhow from another train.
See 3:25 ff for a double-barricade accident. There are some other accidents on this vid including a repeat of the limo one.

I've watched a large amount of these videos just 'cause, and I've seen every kind of dumbness and weird combinations of events to cause these accidents.
Right now the search engines are full of the recent accident, so it's hard to pull other stuff up, but here's an example.

Stop. Look. Listen. That catchphrase has been around since before I was born. People still don't.
And all the engineer can do is hit the brakes and blow the horn.
