Depends what it hits or what it causes to swerve and crash in the goodness knows how many 100s of metres it takes that car to stop.
I have tried to find stopping comparative distances but my head is spinning. One site said 350 metres for a car at 200 km/hr while a truck could stop in 200 at 90. Added to the problem that half of the figures in the various sites talk of mph and feet, whereas others quote km/hr and metres. The bloody AA caps them all by mixing mph and metres.
Even Brake, the road safety organisation formed because of a fatal crash involving a lorry, not speeding but badly maintained, can give me little information and only covers car speeds up to 70.
But what prompted this little debate with us this evening, was your 'thank' (therefore presumably agreement) to JS that 200 km/hr was safe on an autobahn. On a race track maybe but not when they share the same road and sometimes same lanes as vehicles doing almost half that speed. I believe the minimum in the 3rd lane of an autobahn is 110 km/hr. The difference just happens to be the total speed of a lorry. How anyone can consider that
a closing speed of 90 km/hr is safe is beyond me. Hence my comment 'ridiculous'.
