Benoire: The problem with these protests is that it doesnt really take many single occupant cars to gridlock the major roads/motorways in cities and towns and make it look worse than it is, i.e. 10,000 people out protesting would grid lock a large proportion of the city but represents a miniscule fraction of the population.
Is it that many? The linked article counts 200 cars leaving Destiny Church in Wiri, South Auckland.
