If that's the case then presumably getting hit by a Nissan Leaf at the same speed is just as bad and the whole premise is bullshit?

I haven't seen one in person for a while but but a Chevy Suburban is practically flat until 4ft off the ground. A Dacia Sandero isn't nearly that tall. I find it hard to believe that it is the same as a Sandero at least at potentially survivable speeds around 30mph.
