These NCAP tests can be very misleading. I am rapidly losing faith in them.
They tend to penalise heavy mass vehicles. A lorry for example would do very poorly against an immovable concrete block whilst a Smart car does very well. In the REAL world most collisions tend to be against other vehicles or things like lamp posts and trees etc.
A HGV would obviously flatten a Smart car and yet people get a false sense of safety due to the number of stars their car has.
The VW Passat I had on hire was a 5 star - it had airbags all over the place. As a consequence the lack of visibility was frightening - I know my Defender scores very badly - especially on pedestrian safety - but I honestly believe I have much more chance of seeing the pedestrian in the first place!!!
Here is a lorry crashing into a concrete barrier - a bit like an NCAP test. The lorry is totally destroyed - does that mean it's not safe to drive on the road? If it was to be given an NCAP rating on this test it would score 0...........
