I think most reasonable people don’t actually think there needs to be a full ban on these trucks. I do think that most people would agree that there needs to be some restriction/enforcement on where they can park. The picture at the top of the article is a good example, they don’t fit in lots of the angle parking spots right downtown. There are small car spots, there are micro car/motorcycle spots, maybe we need standard sized car spots. Big trucks can park in lots where they do fit or on the edge of downtown (I do that in my normal sized car if I can anyways because who wants to pay for parking?). As for your second to last point, no one’s going to drive 3+ hours from the north Island to Victoria to get groceries especially not in these trucks for $150+ of gas. No one would even drive from Saanich to get groceries in Victoria.
I do agree about the transit though, it’s insane that travelling from Nanaimo to Victoria takes an entire day by public transport and anything north of that is simply impossible.
