I don't think that's true on a highway or similar road. Stopping in the middle of the highway is very dangerous. You cannot blame the 150km/h+ cars to be able to stop safely in all situations.
You will absolutely be at fault and stuck with the bill in every single rear-ending case, good luck arguing otherwise.
It's definitely true on a highway (which is anything that's not an alley), and even a freeway (which is probably what you meant.)

Failure to maintain adequate following distance on any road is dangerous; encountering stopped traffic or needing to stop rapidly, even on freeways, is a regular occurrence.

I don't blame cars for anything, I do blame drivers for failing to maintain a safe combination of speed and separation.
And there's virtually no road, freeway or otherwise, where 150km/h+ (93mph+) is a safe and reasonable speed for any driver, irrespective of separation, so I can quite easiky blame a driver for choosing to drive at such a speed in the first place.
