Is the creator of the meme at left serious? From this piece:

Electric Vehicle Drivetrains Only Have 20 Moving Parts Compared to Over 200 in Conventional Automobiles

This means lower maintenance costs and a radical shift in auto industry job skills.

While most of the media attention focuses on the big picture issues of how green-energy EVs are destined to help mitigate climate change by eliminating use of fossil fuels and will ultimately lower the costs of driving for consumers, there is another significant impact that deserves more attention too. That is the relative simplicity of EV powertrains and implications for lower maintenance costs.

Many EVs don’t even need a transmission. Those that do use a much simpler, single-speed system as opposed to the multi-speed gearboxes in gas-burning vehicles. For example, Tesla’s electric motors only have two moving parts and use single-speed “transmissions” with no gears. The company says its drivetrain has about 20 moving parts compared with 200 in conventional drivetrains. Similarly, the all-electric Chevrolet Bolt has 80% fewer moving parts than a comparable car with a gasoline engine.

And absent the power train, think about other entire systems that do not even exist in EVs, e.g., fuel delivery, pollution control, and exhaust.

What does the most affluent state in America need in its next governor? I’m pretty sure it not a Trump supporter.

Yes, we have traffic, which we hate. But that’s because everybody and his dog wants to be here for our economic opportunities and our natural beauty.

In general, we reject racism, ignorance, corruption, and environmental destruction.

I can’t swear that the content of the meme here is accurate; in fact, most affluent Scandinavians I run across admit that they pay higher taxes than Americans.

They claim that the attraction is that they aren’t forced to live among uneducated slobs where people are dying of treatable diseases with masses of impoverished people living on the streets.

Isn’t there something to be said for that?
