Usually tugboats attend whenever a large container ship enters or exits a busy port, and the tugboats have directional thrusters. Port authorities prefer it that way because it gives them more control (since the tugboats tend to stay in the port).
any idea why tugboats weren't standard issue going out of the port considering the potential damage economic and social of accidentally destroying this critical bridge for Baltimore?

I just saw in a YouTube video yesterday that they actually built a full-size model of the ship (or at least the bow area) and the bit of town it hit. The director didn’t want to use CGI or miniatures. He spent a full quarter of the movie’s budget on that one scene.

The bow is real, the back of the ship is CGI.

> How many pilots, trained or not, really have any experience with a 100,000 ton ship in a crash situation with responses where seconds matter? I would expect anyone piloting such a ship in a harbor/under bridges. We requite airline pilots to train for many unlikely plane failures because the alternative is letting planes crash that we could have saved with better training.
You can train for it, then how many years into your career you actually experience such a scenario are you likely to act instinctually and recover. The best solution would be to improve autopilot assist as it will never forget how to correct (if possible).

If tugboats had been attending Dali, would they have had enough thrust to correct Dali’s course when it lost power?

The release was the decision of the pilot, who remaining in charge of the ship till the accident. If pilots are too liberal in their use of tugs, the ship owner becomes unhappy (because the ship owner ends up paying for them), and if they become unhappy enough, will stop using the port. I.e., pilots are under some pressure to keep the use of tugs to a minimum.
Note that it is probably the pilot who advised authorities to stop cars from entering the bridge minutes before the accident, which is why the only deaths were a team of 6 construction workers working on the bridge.

How common are power outages on ships? I get that the captain might not have responded to it correctly but that seems like a thing that shouldn't happen, at least in my completely uneducated opinion.
Yeah that's not very typical, I'd like to make that point. These ships are built to very rigorous maritime engineering standards.

Energy matters, too. That hypothetical car has the order of 1 kiloton of TNT of kinetic energy. The resulting blast would have been large. (This is about the estimated yield of the Beirut explosion.) I would rather get hit by a slow moving object than a fast one with equal momentum.
If you're moored on the ground you'd be torn apart in both cases
Keep the same momentum but scale the mass down to, say, 200g. Now it’s supersonic, and it will hit with maybe 10x the energy of a musket ball. This would be extremely damaging and likely lethal.
(If you make the mass too small, it might go straight through a person, in which case not all of the energy is delivered.)
How long until Elon offers to dig a new tunnel under the Patapsco river? I bet he already has Boring people on it.
For those who want to hear up to date news, some local sites are: WBAL https://wbal.com/ WTOP https://wtop.com/ Two local news radio stations. Fans of The Wire series may have heard WBAL in the background in some of the scenes, it's a Baltimore institution since everyone wants to get traffic updates.
TRAFFIC AND WEATHER ON THE 8's AND WHEN IT BREAKS! WBAL and WTOP has been a great service to cover the great disarray of Baltimore over the last decade.
WTOP was how I found out on morning commute, though thankfully I work inside the DC beltway rather than the Baltimore beltway.
Lack of redundancy. Also a major contributing factor in the 737 MAX crashes. Redundancy is a low price to pay for peace of mind.
