EVs are heavier, put more wear on the roads (for the same class of vehicle) and more microplastics into the environment from the tires. They don’t fix noise pollution, road safety or congestion.

We need better public transit, not robotaxis.

They may not fix noise pollution, but they seem to reduce it. At least at urban speeds where I can be near them when they're driving, them sure seem to be significantly quieter than gas cars.

Wait, why are EV tires more polluting than gasoline tires?

[-] AHemlocksLie@lemmy.zip 4 points 4 hours ago* (last edited 3 hours ago)

Because the car is heavier overall, which means they put more wear on the tires per mile driven.

Fuck good, let’s have perfect.

Also electric vs gas has nothing to do with robotaxis.

[-] humanspiral@lemmy.ca 2 points 12 hours ago

robotaxis need a lot of electronics/computing and so a large battery. A hybrid can charge that battery, but it is close to 50c/kwh electricity cost. V2G is a more obvious near term game changer. Can pay for cost of car over lifetime, or at least provide negative fuel costs. At any rate, an EV robotaxi will outcompete an ICE one. It also has the advantage of driving to a charging station during any downtime.

That's a fair point, the integrated battery does make managing the equipment easier.

Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
