Cities with high auto use tend to have lower commutes, cities with high metro use tend to have longer commutes. Of course in this case more than any other causation =/= correlation, but just anecdotally you'll find loads of people in Manhattan and Queens with 45+min subway+foot commutes to go a few miles.

NY, the most subway-centric city, has the longest commutes in the US. LA, "the most car centric city" (probably not literally true) tends to have amongst the shortest.

Decommission those NYC subways and replace with private shuttles and busses. Bet you'll see dramatic drops in commute times for NYC. And it'll save incredible, incredible amounts of money.

Los Angeles does not have below-average commute times; it has above-average commute times (the mean is just a hair under 30 minutes).

The NYC subway system is also a red herring. The subway primarily serves Manhattan, The Bronx, and Brooklyn. Of those people who commute into Manhattan from another borough, a plurality come from Queens, half of which has no subway coverage at all; that's for people inside NYC proper and obviously excludes NJ, Westchester, and Long Island commuters.

NY has much, much higher population density than LA, which probably both explains why it was more subway-centric and why commutes are longer.

There's a reason LA has shorter commutes: because highways and car traffic don't scale, and subways do, so it's impossible to get as far as you could with a subway. Los Angelenos still have 45 minute commutes, they just don't get as far and burn a lot of petroleum getting there.

The average commute in NYC is 45mins, which is almost 50% higher than the national average. LA always has a below average commute time.

The fact that LA metro has such short commutes - despite being one of the largest and most car dependent big cities in the world - suggests that highways and private cars do, in fact, scale very well.

While I've never been there, my impression of LA is that it's very sprawling. Maybe not everyone has to go to one central area to work. Unlike Chicago's Loop or lower Manhattan where a lot of the commutes tend to converge in one general area. If few people have the same commute destination, individual cars would be more effective than mass transit.

That problem is already solved, and it doesn't require light rail: Privately run shuttles and busses.

It'll never happen, as it's opposed by (1) Taxi operators, (2) Mass transit operators & unions, AND (3) Do-gooders who don't want private business to succeed where public service has failed.
