The last time this came into prominence was when the Mercedes A Class failed the test and the manufacturers were embarrassed into redesigning its suspension etc.
It now seems that a current version of the Citroën Berlingo type van-with-windows (and Peugeot / Fiat lookalikes) faces the same issues.

IMO this is the time to quote the tennis brat himself. It seems to me that the way to avoid hitting anything is to drive only at a speed etc. Anybody driving like that demo but on the open road and managing to roll a car over is in need of a long driving ban.
As an aside, once upon a time the used to say that the suspension of the Citroën 2CV was so soft you could scrape the roof on the road with all four wheels still on the road
