I wanted to make a smart comment that an ideal world would have us all giving up our cars and giving the roads up to bikes. But then I remembered that Ontario's economy depends heavily on the auto industry. So I'd be riding my bike to the unemployment line, and it wouldn't be a friggin' Surly Krampus either.
But what if I somehow got what I wanted, in terms of cycling infrastructure? What would the city look like after I had my wish list?
It actually wouldn't look too much different. I live in a city of about 300 000, with an old, compact downtown core and sprawling suburbs. I'll bet that most North American cities look pretty much just like mine, with bits of individual character thrown in. Through the downtown core I'd like to see two-lane roads with raised cycletracks on either side. The biggest change I'd make would be absolutely no street parking in the central core, where space is limited. Businesses still need deliveries, though, and I wouldn't begrudge special rules for vans and trucks, allowing them to park where they need, even halfway up a sidewalk or in a bike lane. In those compact cores, you have to make some sacrifices.
Slightly out from the core, I would use painted bike lanes on what I call moderately busy streets (that's a bit fuzzy, but I can't think of a better way to explain myself). I define a "moderately busy street" as one which sees a high volume of traffic, but falls short of those main traffic arteries that people use for commuting.
With the "moderate" streets using painted lanes, I've only left out quiet residential streets, which don't need anything special, and main arterial roads. Often, those traffic arteries have sidewalks that almost never get used, and where there are no sidewalks, there are always large, unused boulevard strips. I would simply double the width of all sidewalks and designate them as multi-use paths. These types of roads usually see almost no pedestrians, and this would give cyclists a chance to be segregated from heavy commuter traffic, allowing everyone to keep moving along.
And this is how my dream city would look. Anywhere at all, a cyclist would have either a lane or a separate path to use.
