This one in South Korea is pretty recent (October 2022).

A special police team conducted an investigation of the disaster within a few days of it occurring, and concluded on 13 January 2023 that the police and governments’ failure to adequately prepare for the crowds, despite a number of ignored warnings, was the cause of the incident.

At first glance the difference in width comes from the front wings, which protruded beyond the wheels in the '22 cars.

So hopefully the wings last longer in wheel to wheel action.

restricting the total amount used and basically anything else makes more sense

Oh you meant eliminate the flow limit, I thought you meant eliminate the fuel itself. And I agree (with the caveat you said, also limiting the total amount).

That won’t happen for 15 years at least, only Formula E can be fully electric.

With an FIA exclusivity deal through 2039 to be the sole EV single-seat series on the FIA menu, Formula E has plenty of time to grow.

Funny story. 50 years ago, to this very day, a revolution occurred in which Portugal took down its dictatorship.

The following day some public administrator/manager sent a letter complaining about people missing work!

Translation after the letter

Your Excellency Director General

I inform Your Excellency that yesterday, April 25, 1974, several employees were absent from work, claiming that a revolution had occurred in the country.

I clarify that this revolution was not authorized by superiors, and no justification was seen for the absences, especially as the service was considerably delayed.

As the current legislation does not provide for absences due to the occurrence of revolutions, I submit the matter to your high discretion, in the certainty that it will deserve due attention.
