Yes, but it turns out it doesn't matter much.

What _does_ matter is the huge reduction in the much more dangerous brake dust, as electric vehicles convert the kinetic energy back to the battery charge via generation instead of wasting it via friction: https://news.ycombinator.com/item?id=44666157

This comment says EVs generate 10-15% more tire dust which is a significant ocean pollutant.

Does anyone know the impact on human health?

Less CO2 for sure but do any of these studies also factor in increased tire dust from EVs since they are heavier and wear out tires faster?

TLDR: Hawking radiation can cause things besides black holes to evaporate.

  Man and moon: 10^90 years
Because the researchers were at it anyway, they also calculated how long it takes for the moon and a human to evaporate via Hawking-like radiation. That's 10^90 years. Of course, the researchers subtly note, there are other processes that may cause humans and the moon to disappear faster than calculated.

About a year ago the Ford CEO (who is also Chris Farley's cousin) explained why legacy car manufacturers could not make good software: each of their cars have 150+ modules, each of them from several suppliers, each of them writing their own software.

For every software change on each module, they have to go to a supplier to ask because of IP rights.

That is why Ford is/was trying to build a new generation of modules with in-house software which they never wrote before.

They also dictate that their suppliers will all use AUTOSAR which is a legacy framework that makes even toggling a GPIO difficult.

  you'll spend a few more months sitting in online seminars while some talking head explains why it takes 6 hours to configure a million goddamn things so their garbage tool can shit out an entire Italian resaurant's worth of spaghetti code just to blink an LED at 1Hz. Except it's not 1Hz, it's 10Hz, or 0.1Hz, or some other bullshit that you didn't want, because you muttered the wrong incantation to the configuration utility somewhere around step 2 out of 800, so guess what, you get to back and do the entire fucking thing again.
