Nothing seems that fast at 50 m.p.h., however, excuse the mix in units, but each of those 200 frames is the equivalent of 10cm or so along the road. At 2000 frames per second then that is the equivalent of 1cm.
I don't make a habit of crashing cars but I did have one glancing head on crash, combined speeds around 125 m.p.h. and it was only centimetres that meant I did not wipe out that family and trash the car I was in.
As a consequence I would say that this 10x frame rate really is quite game changing, particularly for on-coming vehicles.
