Memes

The people in the meme are at about Seattle and NYC, which is a little over 3k miles apart (by car). You'd need to be going 250mph for the entire 12 hours to make that distance. A quick google search says that the maximum operating speed of a bullet train is 200mph, but tests have been conducted at 275mph.

So, you'd need to go non-stop at 125% max speed to make the trip in 12 hours. Even if you went at 275mph, realistically you'd make a lot of stops along the way, which is going to make the average speed a lot lower. Trains are great, but the US is really big.

Bonus fact: a non-stop flight from Seattle to NYC takes about 5.5 hours.

Unfortunately, all the electric train startups were bought up and closed down by diesel train companies decades ago, and the majority of the rail lines are owned by freight companies as well. This is partly why public train transit is so bad: the government has to lease the tracks from the freight companies, who get priority on the lines over public trains, meaning that if there's freight traffic the commuter rail has to wait for the freight lines to go through first.

If it's the UK it's cheaper to meet in a random ass village in Lapland. (Or Mallorca).

That makes sense. Anybody who has less compatible dating options than average for whatever reason is more likely to run into this.
