You’d probably spend a lot of time sleeping overnight in a bus station waiting for a bus for the next leg of your journey. Coast to coast by bus sounds miserable.
Certainly does sound miserable - worse than in a seat on amtrak, let alone a roomette or bedroom.
However you can take the 1310 from LA to Phoenix, then half an hour wait before the 2245 to St Louis, and a 1h25 wait at 0720 for a St Louis to New York.
66 hours with 64 hours on the actual bus, miserable for both you and your fellow passengers.
I was thinking that making a trip of it and taking your time and doing it slowly would probably be the only way to make it enjoyable. As a utilitarian means of travel though, miserable.
