I personally haven’t taken amtrak or via (I’m guessing your in us or canada) i don’t consider traveling on a train wasted time. I can sit and read (i get car sick), i can do work, charge my laptop, use on board Internet or 5g. I can also get a night train and sleep for the journey. America was built by the railways, there is no reason they can’t make a return.

Paying for WiFi sucks. At least in my country pretty much all trains have WiFi. Though if you have 5g in the car you should be able to get it on the train too (at least everywhere the car would). They’re also faster for all but the longest journeys (wish they were cheaper though)

I hope you aren’t watching a show while driving?

Are there other gasses that could be used. E.g some of the noble gasses like argon or neon?
