I guessed a little low.

Edmonton's parking costs are higher than Vancouver's, but the general ease of getting to downtown certainly helps the car usage side of things. People
tend to value time and comfort and I don't blame them. In Downtown Vancouver, it's a choice between either time (advantage transit) or comfort (advantage car).
When I was at Stantec downtown, in my group (to my knowledge) in the peak of things (December 2018), we had: 6 single drivers, 1 carpooler, 4 transit riders, 2 walkers, 1 cyclist, 1 motorcyclist turned transit rider in the winter, 1 motorcyclist turned single driver most of winter that crazy 🞵🞵🞵🞵🞵🞵🞵. The only person I had no clue how he got work was Airboy.
