Non nativespeaker having a question

[Flyingfish2019]

When I say “I am riding“ is clear that I am riding horse or could I also be riding a car or a motorcycle?

I only know about RN submarines...but civvy ones would dive or go to sea.

Not forgetting you can Ride a White Swan (apparently)

“to myself says I“ Which found in both contexts but to me it sounds incorrect. I would make it “and I said to myself“, so said instead of says... and also the word-order is most unusual, isn’t it?

I don't think anyone's answered that question. That's just an old-fashioned way of speaking, in general conversation, no-one says that these days, 'I said to myself' would be a modern version.

The only time you'd possibly hear anyone say 'to myself says I' in modern times is if someone was speaking in a strong local dialect where that phrase was commonly used in a very small area of the country.

You have a bus, train or car ride. (So basically as a passenger.). But you don,t say I rode the but,train or car.

Imho if you said "im going riding", i would assume you meant horse riding. It could mean cycling but i think people would say " i am going cycling" or "im going for a bike ride," for that. I think saying ride a car might be american english? in the uk we would say drive, although a passenger would have a ride.

You definitely can't ride a car!

Tell that to Chuck Berry.

I don’t think anyone would say they’re riding a skateboard, they’d be skating

People who don't skateboard usually say skate, but people who do say ride. Same for the other board sports.

Thinking about it, I reckon in British English we do use "ride" for cars, planes, tanks etc, but only for a pleasure trip. "We went to a military event and Gran got a ride in a tank!". So as a pp said, if you are riding IN something, you are not the driver and it's not for the purpose of getting to a destination. That fits with the use of "ride" for fairground rides as well.
