Survivorship bias?

[–] yimby@lemmy.ca 24 points 2 months ago (16 children)

Two facts:

  1. The average occupancy of a car in my North American city is 1.2 people per car. This does not vary much by city.
  2. Autonomous vehicles will almost certainly be worse for traffic than human driven cars. They will circle empty with no passengers and drive to pick up passengers empty (dead heading) even with a fully rideshare system. If there is widespread private ownership of autonomous vehicles (and you bet your butt that car companies will campaign for this aggressively to keep sales up), the dead heading problems only multiply. If you don't believe me, look up any recent literature on the topic: by most accounts it will be worse, not better. Dead heading is only the tip of the iceberg of problems there.

I don't know, if I were surprised by a panther I think I would also be shocked and say holy shit, haha. How should I react to not get hirt?

Ellipses... definitely.

Sentences ending a full stop. Somewhat.

Very context dependent though

i.e. as "in effect" is even easier

I as pro-EV as the best of them. A cradle to grave emissions drop of 40% is a great step forward on reducing transport emissions (public transport and active transportation are a whole other aspect of this we'll avoid here). However, characterizing the energy gap for EV charging as a non-issue is disingenuous.

You've correctly pointed out that peak hours are when the grid is most strained and vulnerable. Well, if most everyone who drives to work starts charging their EV when they get home from work, that is at the highest peak of the day: around 5-7pm. It's the addition to the peak curve that's the real concern. In most places, that means triggering on fossil fuel burning facilities to meet that peak demand. It also means increased peak loads on the transmission infrastructure that could overwhelm it.

That being said, there are some simple solutions: e.g. charge EVs on off-peak hours, smoothing out the demand on the grid. Where I live there is already an incentive to charge overnight in the form of ultra low overnight rates. I'm sure we'll find the solutions, but please don't pretend it's not a problem.

The answer to why is billions of dollars of subsidies to the animal meat industry.

Yes it affects parts too, at least batteries. Stifling electric car production isn't enough, ebikes get caught in the crossfire too.

Reminder to remove the ?si= and everything after in your youtube links. It's a tracker uniquely tied to you and your watch history and the links work fine without it.

They're a little cagey about exactly where the crossover point lies relative to the likelihood of devastating effects on the planet.
