It's not going to be bicycles that are the top contributor to vehicle
reductions, but if they can contribute just 1-2% it would be
significant.


What is the relevant definition of "significant"?

Between 2016 and 2017, annual U.S. miles driven increased 2.8%.
https://www.npr.org/sections/thetwo-...-u-s-last-year

If bicycles reduced that by 1% to 2%, things would be back to where they
were in about four to eight months. I wouldn't call that significant.

Some people in r.b.t. have a distorted view of the value of bicycle
infrastructure since they are perfectly happy to ride without any.


Hmm. We just joined some friends for a ride of a bit over 30 miles.
Maybe five miles were on a near-empty MUP. That was nice. The rest was
on perfectly ordinary roads with no special bicycle infrastructure. That
was just as nice.

I thought people who are perfectly happy to ride without special
infrastructure are called "cyclists."

That's not been the case in NYC. There have been yearly cordon counts dating back to the 1960's. All taxi trip origin/destination and elapsed time data has been available since 2009. This permits estimating speed (congestion) within any area in the city.

The results show that within Manhattan's CBD (below 60th St), cordon counts across the CBD boundary are at 30+ year lows. The results also show that average speeds are also decreasing.

In many cities, what is contributing to increased congestion is the
decrease in the use of public transit and the increase in the use of
services like Uber and Lyft.

https://www.citylab.com/transportation/2017/12/how-to-fix-new-york-citys-unsustainable-traffic-woes/548798/

Investor-subsidized ride services like Uber and Lyft versus
taxpayer-subsidized public transit. The former is not sustainable,
Uber's loss jumped 61 percent to $4.5 billion in 2017, but if they can
eliminate the cost of paying drivers with the use of self-driving cars
they could turn things around. Lyft is not doing quite as badly, their
losses are at least decreasing.
