I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
An oval stock car racing circuit in rural Sussex
Loads of parking but there may well be restrictions on race days. It is a popular venue that sells out regularly
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 23/02/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location.
