750 a year? Wtf is this retard smoking. Cost for land, hay storage, water, vet, and farrier. Human time cost to feed them twice a day, get rid of or spread the shit. Blanket, saddle, bridle. You're looking at a few thousand a year minus the time sink.
Source: I know a guy who trained his horse to ride from the bar to his house on its own. Cops still pulled him over because he was sleeping on the horse.
I feel hay and grass may end up more expensive than anon thinks... For grass, you need a big place where your horse can graze. Anon either is such a big landowner or intends to rent such land, but it won't be cheap. Then the hay for when the horse is kept indoors... Gotta be a lot of hay. And the means of bringing and storing the hay may be of non-negligible price. Then there are vet bills, because horses can get sick or injured...
I knew someone who owned horses long ago. Well, more like someone whose parents owned horses since we were kids. They even had a coach that these horses could pull. But they didn't use it as a means of transportation unless just doing a simple roundtrip for leisure, and there's a simple reason for that: You can't leave your horse for hours on a parking spot. You can tie it up somewhere maybe, but not for a long time, there aren't many places fit for leaving horses nowadays.
From what little I know about horses, almost all your time is spent trying to make sure they don't kill themselves. I can leave my vechile outside in the cold for weeks at a time and not have to think about it.
Horses can't be beat in the post-apocalypse for speed, but for most other things you probably want a donkey or mule.
Far sturdier, easier to handle, can eat anything, and has no regard for wolves.
Where the fuck you store it though? A shitty car you can park anywhere, a horse is gonna take some space. Especially for us poor fucks where the temperature drops below freezing for part of the year. Car just maybe not gonna start today, a horse might not start ever again.
The lowest emission vehicle you can own is an electric bike.*
Will cost 1–4k and way less than $750 annually in maintenance. Can get a road-only one or one capable of going off-road. Does not require insurance or licensing. Can't legally drink and ride, but you're very unlikely to get caught if you do, and unlike drink driving the risk is overwhelmingly only to yourself.
Keeps you fit and healthy by being active in your daily life.
* yes, lower even than an analogue bike, because the electric motor is more carbon efficient than human muscle power which requires eating more.
I know it's a joke. If I was taking it seriously: I don't want to spend several hours getting to a job that's already say, an hour's commute. And then storing the horse at the job and then several hours back.
0 emissions? Methane from cattle is a large contributer to climate change. If we had as much horses as we have cars, the amount of methane would be too much to handle.
