What people often tend to ignore in the car vs. bike vs. transit is that it completely ignores the other growing uses of roads...transportation of goods and services
You like your Amazon packages delivered to your house? A delivery van is going to drive that to you.
You like your Skip the Dishes? Someone is going to deliver that to you.
If you are any kind of business in Windermere like Safeway, PF Changs, Walmart, Canadian Tire, etc and you rely on products to stock your shelves or restaurants, none of that is coming on a bike or a bus in a bus lane.
The SW is the most explosive growing side of the city and to suggest that Terwilliger Drive should or shouldnt be expanded because of passenger vehicle use vs bike vs transit use completely ignores a massive other reason that roads need to be built...the transportation of goods and services, especially in the fastest growing area of the city.
