On a similar note even in this Country events like that have happened, and because there was no serious outcome I suppose it was washed aside ah well no one else got hurt as a result of these three instances I remember well. Cadwell Park around 1978 Famous Dutch Wil Hartog rider had to avoid an ambulance which came on the track in front of him on start straight before the race was stopped in fact Wil could have been the ambulances casualty. Silverstone GP 1980 Patrick Pons fatally injured on Beckets while being attented to a Doctors car crosses the track from infield to the rider and parked on the crash area on the exit of corner trackside race wasn't stopped. Oulton Park 1981 Course car came onto track during race in front of leading riders going into Old Hall they all braked suddenly only after several more moments was the race stopped a rider was fatally injured at Knickerbrook. All these examples could have lead to more tradegy. Even Mallory has had a few close ones where the paddock has let traffic out as a race has started. Not very nice... but should be a thing of the past
