Observations on cycling in Atlanta vs New York, ctd.

14. The perceived risk of getting 'doored' while biking close to parked cars is much, much lower in Atlanta. In New York, in my experience, a shockingly high proportion of parked cars have drivers sitting in their seats (doing what, I don't know). This might be because a larger share of NYC drivers are performing business stuff that requires precise scheduling. The lack of parking availability means that there's an incredibly high variance in the time it takes to find a spot. If you need to be parked and meeting someone at a specific time, you'd better start the search very early. A necessary consequence of that strategy is that lots of people get lucky and have to sit and wait in their cars. This sucks for cyclists.

Alternatively, it may be due to something more complex and subtle. Perhaps the congestion, lack of parking availability, or general stressfulness of driving in NYC means communication and planning tasks that ordinarily would be accomplished at the middle or end of a car trip need to be done before it begins. Whatever the reason, in my limited experience in Atlanta so far I haven't felt nearly as exposed while biking in the 'door zone', which is nice.

Brilliant ebook innovation

Via Marginal Revolution, an author is running a promotion whereby his ebook will be available for 24 hours only. This is a great example of something often talked about but rarely observed: leveraging the novel technological form of ebooks to innovate in the medium. While ebooks certainly enable some obvious innovation on the back-end, a really fresh and new customer experience has been lacking.

This destructible ebook thing is very reminiscent of Snapchat's schtick, sharing its layering of both social media and gamification onto a more typical technology. The growth of compressed "happening now" marketing events that spread virally on social media has yet to touch publishing--until now. I could easily imagine authors like JK Rowling or George RR Martin releasing short stories or novellas on a time-limited basis.

Very good questions to ask

The real question was whether low-income residents moved away from “gentrifying” neighborhoods at a higher rate than they did from nongentrifying neighborhoods.
That's from an excellent piece in Slate about the vagueness and questionable utility of the concept of gentrification. Of course the opposite of gentrification--neighborhoods that stagnate and decline--is a much bigger problem that doesn't always attract enough media attention. I agree with mostly everything in the article, although the idea of community value in neighborhoods not being priced into the property exchange markets doesn't really come up.

Observations on cycling in Atlanta compared to NYC

1. Atlanta is less dense and more spread out, meaning overall the utility of cycling is reduced (there are many important places that seem essentially unbikable). Outside of a few specific neighborhoods a car is basically required.

2. Bicycling in NYC is a competitive substitute for public transit because distances are very small. While moving trains and buses are faster, the fixed costs of walking to a station/stop and waiting are simply crushed by cycling, whose rapid movement begins immediately from any location. Add to this the fact that cycling is more point-to-point (no connections). Cycling in NYC also beats out travel by car, which must cope with terrible congestion and parking problems.

3. The distances in Atlanta are much greater, so the fixed costs of transit use are more compensated by the speed advantage once the train/bus gets rolling. This effect is somewhat offset by the added time required to get to a station/stop.

4. Cars aside, public transit options in Atlanta are so limited that cycling here (vs. NYC) may in fact be comparatively more valuable. This is mostly due to the tremendous coverage advantage cycling has over the public transit network.

5. There is much less cycling infrastructure in Atlanta (bike lanes etc.), but biking here actually feels safer than NYC. This is due to a number of factors.

6. Roads are less congested, so cars have much more physical space to safely overtake a cyclist by providing adequate passing room. Possibly related, the lack of congestion means motorists are more relaxed at stoplights and seem to accelerate much less aggressively compared to NYC (drivers in New York are stopped in traffic so often that they seize any open-road opportunity to zoom unsafely).

7. There genuinely seems to be a cultural difference that makes motorists more respectful and deferential towards cyclists. Possibly the lack of cyclists on the roads mean motorists aren't well-accustomed to car-cyclist interactions and take a risk-averse approach. This would cut against the conventional wisdom that more cyclists means safer cycling. Bottom line: NYC taxis are incredibly dangerous and fear-inducing, and biking in a city without them counts for a lot.

8. The quality and upkeep of roads and pavement seems to be much better than in NYC, whose infrastructure is crumbling and over-capacity. Fewer potholes and hazards means a less erratic biking line, meaning a safer trip.

9. Better weather.

10. Atlanta has many fewer pedestrians competing for space on bike paths and street crossings. This mostly eliminates a big source of fear and confusion, and leads to a more calm and pleasurable biking experience.

11. The transportation benefits of Atlanta's Beltline greenway network are overhyped. Although it links several decently walkable neighborhoods (and is expanding), its advantage over the typically-empty Atlanta roads and streets is only moderate.

12. That said, the economic, cultural, and urbanist benefits of the Beltline simply blow any other bike path out of the water, including the Greenway in Minneapolis. Atlanta is so starved of walkable, pedestrian areas with mixed commercial and residential development that the Beltline--ostensibly a transit project--is most valuable as an economic engine. The Beltline has more commercial and residential entrances facing the path directly than any other bike path I've yet seen. In context, however, this great value is largely an artifact of Atlanta's absolute lack of walkable dense neighborhoods.

13. Contrary to popular opinion, it is in fact possible to bicycle from the central downtown area of Atlanta to Hartsfield–Jackson Atlanta International Airport using a small number of low-traffic frontage roads along the MARTA train path. It takes approximately one hour.

Is Sirius XM in a death spiral?

I recently had the experience of being at a diner for an extended period, during which time the satellite radio provider Sirius XM was playing. What struck me was the surprising quantity of advertisements that played in between songs--advertisements for Sirius XM subscription services and various highlighted stations.

The concept of satellite radio is simple: businesses (and to a lesser extent individual customers) pay Sirius to provide ad-free radio. Needless to say, the more advertisements Sirius interjects into its stream, the less valuable the subscription service becomes relative to the free + advertising radio models out there. If Sirius XM is introducing ads hoping to lure new customers, they run the risk of alienating existing customers on the margin.

In the worst-case scenario, this process edges into a 'death spiral', where the loss of existing customers forces Sirius to include more ads to cover the revenue losses.
