You may have seen the Yes on G campaign citing that injury collisions have increase 33-34% on the streets closest to Great Highway since the closure to private vehicles. When stats are being used to support arguments without transparency into the data and methods used, I always wonder: are they hiding something?
With the chart that @SelenaC10705 shared today, I have now been able to exactly reproduce their data. Unsurprisingly, the claim is misleading.
DataSF provides public data on injury collisions. Using this data set, I was able to determine that the Yes on G data uses the following road segments:
1. Great Highway Extension, Upper Great Highway (pre-closure), and Great Highway up to the point it turns into Point Lobos
2. Lower Great Highway and La Playa
3. The full length of 46th, 47th, and 48th avenues, including the portions in the Outer Richmond
4. The full length of Sunset from Lake Merced to MLK
Why choose such an arbitrary set of roads, including portions in the Outer Richmond? I don't know, but I don't think the Yes on G data tells the full story.
The rise in collisions drops to 23% when I filter out collisions north of Lincoln and south of Sloat. Collisions actually drop when looking at all streets within bounding boxes in the Sunset between both Great Highway/36th and Great Highway/18th. In the first bounding box I looked at in the Outer Richmond, collisions are actually up 50%!
Street safety is incredibly important to me. My family drives, walks, runs, bikes, scoots, and skates the streets and paths of the Outer Sunset, Sunset Dunes, Golden Gate Park, and the Outer Richmond regularly. One of my kids goes to school just off Sunset Blvd, the other over in the Richmond near a lot of those collisions.
I don't think the collision data proves anything. Collisions are sparse relative to vehicle miles traveled. I don't think this data proves that the closure has made streets less safe, and I don't think it proves the closure has made streets more safe.
I do agree with the Yes on G campaign on one point: we can have great parks *and* safe streets too. I just don't think destroying what is rapidly becoming a beloved park is the way to do it.
I propose the following compromise: Vote No on G, protect Sunset Dunes, and then let's get D4 and the west side to rally around street safety and traffic flow improvements at the most dangerous and congested parts of our road network.
Let's stop complaining to @alankennywong about the Great Highway and instead light a fire under his ass to deliver us street safety improvements everywhere else in D4.
And please, let's stop throwing data around without showing our work. We are better than this, San Francisco.
@mikelouie@markasaurus Elementary school language programs are where SFUSD reallly shines but they can’t cater to those families because those are also the ones most likely to go private if they don’t get a spot.
@bobbyfijan@ChuongIsHere Were you aware of the attendance area tie breaker for the school lottery? It is unlikely, that you would not have been given your AA school if it was on your list.
@NaithanJones October is historically SF’s summer. The musicians that come to Outside Lands in August, do appreciate mother nature’s natural AC aka fog.
@frank_smith1111 The original better market street plans included a separated bikeway by taking some space from the existing large sidewalks.

@HappySoccerGuy Is MLS Go popular in other parts of the country? In SF, it was rolled out in the last year or two and run by a local club but has way less traction than the incumbent Microsoccer rec program.
@PaulSpacey This is quite skillful if he did flip on purpose. He is on one leg and it doesn’t appear like he jumps to sell the “flip”. Although if he just left his leg planted there he could have suffered a knee injury.
@Kazanjy Most families get a desirable result. Each address is assigned an attendance area school which gives your child a high priority tie breaker for that school. The benefit of the lottery and why many families that would typically go private is # of language immersion programs.
@jc_playmakerWNY So if girls recruiting goes big overseas, ECNL’s biggest selling point is gone and they can’t let that happen because it would be bad for business?
@jc_playmakerWNY I did not know till now international recruiting was so big with men’s soccer already but it makes sense given what has happened in men’s basketball with the expansion of recruiting overseas players.
