I was honored to participate in @NASEMTRB’s panel “Steering the Titanic: Decarbonizing #Transportation” yesterday. Feeling energized by the insights provided by participants. We are greater than the sum of our parts! #TRBAM2023 #TRBAM #TRB

@Tesla A lot of grid-connected equipment in the background right of that picture.

@TrungTPhan Trump's inauguration crowd was bigger.

🤣

[Rob Graff @OptimisCynic]

@elonmusk Nah. That wouldn't happen. It is all public information. Give it a rest.

[Rob Graff @OptimisCynic]

@elonmusk You are out of your mind. And you are ruining the Tesla brand.

@laurenboebert How does the right want kids to identify?

As a (very) active user who doesn't want this site to fail, I couldnt give two shits (let alone $8/mo!) about a blue check. But an ad-free user experience where Twitter engineers focus algorithms on serving most informative content I want to see instead of ads, THAT I'd pay for!

[Rob Graff @OptimisCynic]

@teddemop I say Matte. Looks classier, and can be seen easily I'm bright light.

[Rob Graff @OptimisCynic]

@NateApe34 @JohnathanPerk @elonmusk Well, if you say that, you would be wrong.

[Rob Graff @OptimisCynic]

@WardyIii @TheDemocratDrew @Freedomautospa @tribelaw All of the procedures are public record. I suggest you serve as a poll worker and see for yourself.

[Rob Graff @OptimisCynic]

@elonmusk Distracts the public and the government from addressing more important issues.

[Rob Graff @OptimisCynic]

@KimJ333 @AboutChesapeake Actually, I think the easy access to a gun is to blame.

[Rob Graff @OptimisCynic]

@elonmusk Eating alone again, Elon?

[Rob Graff @OptimisCynic]

@TheDemocratDrew @Freedomautospa @tribelaw As a poll worker in Pennsylvania, I can attest to the integrity -- many checks and cross-checks to assure an honest process at the polls.

[Rob Graff @OptimisCynic]

@tribelaw The first sentence is very sad, but increasingly close to accurate every day. The ruling against Trump regarding his taxes is a small step in the right direction.

[Rob Graff @OptimisCynic]

@elonmusk I thought you were instituting a council dedicated to addressing such questions. Is the twitterverse your council? I think you can do much better.

[Rob Graff @OptimisCynic]

@Ollie_Cycles I agree that street parking should have a higher price than transit. But transit fares are not the primary "cost" of transit for most. Frequency, convenience, time to get from here to there, and if you can get "there" at all are bigger reasons people chose driving over transit.

[Rob Graff @OptimisCynic]

@energysmartwv All that said, developing a low-cost, low-overhead, way for those without dedicated off-street parking to charge their vehicles is absolutely critical to the success of EVs. More work is being done, and there are some great pilots (e.g., NYC, LA) that we need to learn from.

[Rob Graff @OptimisCynic]

@energysmartwv I can't find the exact code now, but I understand that the NEC requires that 240V public charging cords be permanently attached, and there is not an approved connector in the US as in Europe. Also, unfortunately, theft of valuable copper is much bigger problem in the US. [more]
