Why do British people have such a dim view of Automatic cars? (feddit.uk)

I've been driving an automatic since I passed nearly a decade ago. In that time whenever I tell anyone I drive auto, it's usually met with some level of derision. I think that attitude is changing, but I'm still kind of confused by it in the first place.

Why?

I've decided to do some research on eCVT. I was surprised at its actual implementation. Toyota Prius, Ford Escape, and probably Honda Accord does this.

Its basically planetary gear magic. A computer can control two or three inputs, while the outputs are hooked up to the wheels of the car. By changing the speed of the variable input (likely the electronic engine)... the effective gear ratio of the "constant" input (likely the ICE engine) is modified. In the most extreme case, the variable input runs backwards to have the "overdrive" gear ratio.

It seems like the Honda Accord is a planetary gear eCVT system. Planetary gears are always so cool, I didn't realize that a CVT could be implemented with one (albeit with a hybrid vehicle where you have 2 or more powered inputs).

EDIT: it appears that you are correct. Honda's Hybrid system is different than what I'm familiar with (which is what the above video demonstrated).

So you're right with regards to Honda Accord Hybrid. Very interesting. Its always surprising to me how different car companies are with their implementations.
