I was going to say, 90km/h is 66mph, that's almost 50% faster than the Euro NCAP stuff.
And even then you're talking about a scientific yardstick not real-world conditions.
My Dad had a serious accident in a Mk2 Polo breadvan, involving a stolen Vauxhall Cavalier. It spun him around in the road, buckled the roof and flattened the front end. My Dad walked away.
I think it's a bit worrying that plenty of motorists these days (not targeted at the OP) jump into a five star car and assume they'll be fine in an accident. Safer, yes, but it's still dangerous having a crash.
