Car tore past us at terrific speed.
Few miles down the road some cars had pulled up and a frenchman was flagging down vehicles asking if anyone had a mobile phone (yeah this long ago).
Car that sped past us was was upside down some distance into a field a little below the road level.
Guess something unexpected turned up.
Many years ago had a little white car going screaming past us on the M3 IIRC - few miles further on a snaking mess of skid marks and the car was literally wedged in the fork of a tree at the side of the road some distance off the ground at the side of the road. Looked like everyone had walked away from that one though.
