The rule says:
188.8.131.52 3. Operations must not be in, or in the close vicinity of a motor vehicle. No part of the
station may be connected in any way with the motor vehicle. However, the use of a bike (non-motorized) or animals to enter the Activation Zone is permitted.
The older version says:
184.108.40.206 The method of final access to the summit must be non-motorised. Operations must not be in, or in the vicinity of a motor vehicle. No part of the station may be connected in any way to the motor vehicle.
The rule was re-worded to indicate that a degree of separation was needed, “close” was put there to cover the car-park situation, and to imply that somebody using a handy and sitting on the bonnet of the car would be breaking the rules. Has this been done? Yes. Have people broken the rule by operating from inside the vehicle? Yes, on more than one occasion. Many of the rules are closely specified because there are people who will happily bend them to breaking point and swear blind that they were following the rules! Incidentally, vicinity itself is vague which is why it was qualified with “close”, some people would regard a mile as the vicinity!
If Mt. Dale can only be activated from the car park (there are other summits elsewhere like that) then you accept the situation and operate as far from your car as the parking area permits. We don’t expect miracles, only that you consider how the “Golden Rule” interacts with the site conditions and do your best.
