Greyhound nyc to dc is like $20 and has a dozen buses a day. Plus you have Amtrak. Why take an Uber?
So I assume that's one reason to take an Uber? I was going to look into a charter anyways based on that advice.
Amtrak I'm more familiar with but at least in California it's just incredibly slow.
I think there is more than one reason that Americans "never give it a chance".
If you don't need to be at your destination for a particular time then Amtrak is nice a way to travel if the route works, especially if you get a cabin.
