This is a discussion forum. We're all engaged in casual conversation here. But why are you taking offense when others reply back to you on the same level? Why are you making a big deal re: evidence and verifiable figures if you didn't bother to provide any yourself?
I don't remember taking offense and found it surprising that you think I did. No doubt due to poor wording on my part. I am old and the old tend to become blunt as they age, and I am not exempt. Don't confuse bluntness with anger.
If someone had asked me for evidence to support my original response I'd have been delighted, actually. As it was no one did that, so I merely responded to replying messages that they didn't provide any evidence, which I think if you read them carefully, you'll find is true. It would be nice if someone before now had pointed out the lack of evidence in my original post. That would have been a much better way of answering me, at least from my point of view.
I would think that it should be fairly obvious that diverting some or all the traffic from North of the Hat to the Saanich penninsula would increase the number of cars travelling down the penninsula. Adding more traffic to a road doesn't seem likely to reduce it's overall volume, at least in the near term.
I know from driving the road a decade and a half ago that traffic jams were common then, especially when the ferry unloaded. I talk to people who drive it daily and complain about the density now, so I suppose things have not changed much. Whether the increase would or should be acceptable to the people who drive the roads there now is a reasonable question. My experience is that people don't like change much, and would complain even if the increased traffic level were not unreasonable. People who are upset about something like that tend to complain to local politicians and are more likely to go out and vote against them. Politicians don't like that.
I would think that if such a proposal came from, say, the Provincial government, and based only on my experience of how politicians of all stripes act, that there would be a real ruckus, such that I would be surprised if the idea would get anywhere. I have been wrong before, of course.
