If you are moving a full car of people, it's probably the best way to get around. However the average occupancy of a car is 1.2 people. The vast majority of cars have just 1 person, often driving less than 5 miles which is an easy distance to cycle.
Having more people cycling means the roads are less congested for the people who really need to use them. And with less people driving and more cycling, it should hopefully get safer.
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 really hope in the next few years we see a revolution in short distance transport. Most journeys are less than 3 miles (if I remember correctly, could be 5) a perfect distance for e-bikes, e-scooters and normal acoustic bikes. Hopefully at least some places capitalise on it
Metals are made of crystals, they usually defourm along the grain boundaries and fatigue cracks also grow along them. By eliminating those boundaries you reduce the chance for fatigue cracks and make the overall blade stronger.
I wish the checks could just be done on the train, I'm not sure what the issue with it is.
