The objection by the Watsons and Mrs Wilson was not to car and motorbike racing events, which take place on the track on about 45-50 days-a-year, but to "vehicle testing days" and "track days", when members of the public drive cars around the track all day long at high speed.
What the hell is the difference?!
If anything the days they object to would be quieter with fewer traffic and more road going cars on the track.....
