This is pretty apples-to-oranges. You see things like this in a lot of less dense U.S. areas as well. But in the crash example, it's right in the middle of an interchange, with the lane needing to form and rise quickly. Additionally, the gently rising metal barriers aren't safe in many situations because of their ability to launch cars. That's why they've been replaced by crash attenuators and sand/water barrels. Unfortunately the crash attenuator wasn't replaced after a recent (<1 week ago) accident, ensuring the next accident was fatal.

Here's an accurate U.S. analogue to your example: https://www.google.com/maps/@41.0286482,-102.1517159,3a,75y,...

Meanwhile, here's a Dutch example: https://www.google.com/maps/@51.9305956,4.4371182,3a,75y,66....

Turns out sometimes you need crash attenuators because space isn't infinite. Also, there's no grass in sight here.

Here's another example: https://www.google.com/maps/@51.9239112,4.4203482,3a,67.8y,2...

No sloping barriers, because they're not always safer.
