This reminded me of the orangutan driving a golf cart: https://m.youtube.com/watch?v=DJsn1QivbKM

He has mastered it. He clearly understands the concept of roads vs sidewalks. He can drive using one hand. And most importantly, he obviously has a great time doing that.

I don't understand.

Someone, at some point, said lets see if the Orangutan can drive the golf cart, and presumably no one said "NO! That's an awful idea"...

Then not only did it learn, it got good at it and seems to enjoy it...

I just really don't understand how this came about. How did it learn to do this. The initial phases must have been just constant crashing into stuff. How on earth did it ever get past this without a teacher being able to communicate with it.

I have so many questions.

Why would you assume that?

It didn't learn by trial and error, it watched and copied another ape.

Golf carts aren't massively complicated.

Probably same way I learned as a kid on my grandparents ranch. Start by letting them steer but correct as needed. Eventually they steer by themselves. Then introduce gas pedal.

Not sure but there is video of some guys driving with it. It's on at the zoo of Dubai Royal Palace. Orangutan's are supposed to be pretty smart - it could probably watch humans press the accelerator and turn the wheel and figure it. https://youtu.be/WSR_4qyz7CY?t=285

bees will push balls around just for the hell of it - they trained the bees to push the balls and then took the rewards away and gave them unlimited pollen and sucrose and the bees kept going back to the balls. they just wanted to mess around

Are you sure the steering wheel is actually hooked up? There are times especially toward the end of the video where he turns it and I don't see the expected swerve (even a small one) from the cart.

Along somewhat different fitness gradients, though. Meaning we've evolved some distance from them.

In fact, given the dimensionality of all possible fitness gradients, our direction of evolution is likely near-orthogonal to theirs.

"One day, a student noticed something strange: One of the rats in the group trained to expect positive experiences had its tail straight up with a crook at the end, resembling the handle of an old-fashioned umbrella."

For anyone having, being friends with, are interested in cats will recognize this behavior. If you meet a cat on the street and it raises its tail like this, it will also probably come up to you. A cat that sweeps the tail back and fort, often with the end of it a bit jerky is probably afraid, angry, hesitant and does not want to engage. It should be left alone unless you want to feel the sharp end of those retractable razor blades.

Cats also use the same patterns between each other. And interestingly some dogs use the same patterns too. Tiger puppies seem to do this also (as seen in documentaries). So, at least to me, there seems to be common 'language' to express feelings and interests between some animals equipped with tails.

I would have thought this should have been a known thing, possibly even for the driving rat scientists. Anybody on HN that have some references into known ´tail language´?

I don't think there's anything "lost" about having a hobby, or passion and love for your pets. I find it endearing and sweet.

Maybe it is hard coded in sentient beings to enjoy moving at speed with very little energy expenditure. To quote C.S. Lewis in the The Last Battle-

“If one could run without getting tired, I don’t think one would often want to do anytrung else?”

As a runner, I agree. :)

Fish can drive cars too.

https://www.cbc.ca/news/science/goldfish-driving-1.6309485

>>> Surprisingly, it doesn't take the fish a long time to learn how to drive the vehicle. They're confused at first. They don't know what's going on. But they're very quick to realize that there is a correlation between their movement and the movement of the machine that they're in.

My armchair biologist thought is to wonder if there's a common thread of balancing (on water currents, air currents, slippery surfaces, etc) that translates into fairly easily understanding how to direct vehicles.

Of course this fits right in with the thread's theme of animals driving, and I don't want to be a spoilsport, but this article has me not too convinced about the bold claim it makes.

As good as it sounds, I have my reservations about it showing "that a fish has the cognitive capability to navigate outside its natural environment".

Rather it seems to me the fish is just swimming in the direction of the treat, as it would do _inside_ its natural environment, and the car translates that directional push - I don't see a real "driving" coordination in the sense of a motoric abstraction based on a learning of cause and effect.

I doubt the fish are in any way "aware" of what's happening, or even that it's happening distinctly outside their environment. They're just swimming instinctively, adopting to what I imagine might a feel like a strong breaking current and a boop on the nose. Some might be more adept at this than others. After all they're captive animals that probably don't have much experience navigating challenging environments, not even aquatic ones.

I highly suspect "driving" via levers or buttons like the rats do would be beyond of what can be reasonably expected from a goldfish brain anyway.

As a kind of mental cross-check of the claim, I'd expect, say, a moth to be able to "drive" just the same way towards a light - and it would be pretty obvious there's no deeper cognition involved.

Pfffft, nobody is banning driving. Self driving cars are not going to be rolled out that widely for a while. Also, moving away from car centric infrastructure doesn't mean that cars are getting banned. That's such a weird US centric take I see way too often.

Here in the Netherlands, we arguably have some of the most bike and pedestrian friendly infrastructure in the world. Guess what, we also have a very well respected car infrastructure with high quality highways and connections.

Focussing on other modes of transport isn't banning cars, it is making cars optional for those who choose to do so. Or worded differently, it gives people a choice.

With that out of the way, the title here on HN is misleading. It is not so much about driving but enrichment in general.
