> At a certain point doesn’t creating a preference for pedestrians and cyclists actually end up being a preference for wealthier people who can afford to live downtown, versus those who need to access the city but can’t live within walking or biking distance?

Reducing the number of cars (and therefore traffic) on the roads will benefit everybody, especially if cars and bikes don't get in each other's way (such as in the case of dedicated and protected bike lanes).

> Note that bicyclists and skateboarders also slow down busses, which are what lower income people use to get around

I don't think this is true. Busy streets and traffic jams slow down buses.

You seem to have a rose-tinted view of the world we live in.

  Have you ever had to commute in less-than-ideal 
  conditions? 
  Heavy snow? Sleet? Black ice? 
  Have you ever lived in places that are not 
  perfectly flat? or lived in places that 
  are hot that make bicycling unfeasible?
  Did you have sporting gear / work gear that
  you had to lug? Did you know some people have
  to fetch their own gear to work
  Did you have to take calls during transit?
  Did you know its common practice for employees
  to call into meetings during their commute and/or 
  help assist operations via conference calls?
  Have you had to shop for more than a baguette 
  or a bagel at a store? You know how cumbersome
  that gets for even a family of three? 
  Do you have the slightest clue how much casual 
  violence and crime happen on public transit?[1] 

Not to belabor the point but there simply are dozens of cases where bicycles or public transit just don't cut it. Not to mention the hygiene, personal safety (from other passengers for example) and personal space aspects involved in someone choosing a mode of transportation other than public transit or bicycling.

Ride-sharing, autonomous vehicles and emission-free vehicles should all alleviate the issues we currently face with traffic, parking and accidents.

However doing away with cars or vehicular traffic is just pollyannaish madness.

> Have you ever had to commute in less-than-ideal conditions? Heavy snow? Sleet? Black ice?

Routinely. The only weather I have encountered that is really problematic is when it's very windy.

I would also note that the conditions you list are also the conditions under which you shouldn't even be driving.

> Have you ever lived in places that are not perfectly flat? or lived in places that are hot that make bicycling unfeasible?

I live in a very hilly area. I don't know how hot you consider "unfeasible", but we top 100 degrees pretty much every summer.

> Did you have sporting gear / work gear that you had to lug? Did you know some people have to fetch their own gear to work

Yes, I do all of that. An urban bike trailer (easily folds up to briefcase size when needed) solves those problems.

> Have you had to shop for more than a baguette or a bagel at a store? You know how cumbersome that gets for even a family of three?

Again, trailer.

> Do you have the slightest clue how much casual violence and crime happen on public transit?[1]

That's extremely dependent on where you live. Where I live, there is nearly no such problem.
