>>2030256>speed (fastest form of travel for 150-300~kms due to the bullshit that is flying)Flight is faster and the idea that HSR won't have TSA/security nonsense is pure fantasy
>comfortYou only get "comfort" in trains that aren't full and running non-full trains is inefficient both in terms of fuel and profitability. Worse case you get something like video related.
>eat, do workYou can do that in planes. Plus the idea of eating in trains as an advantage of driving is a weird flex. Train food is like airline food, it's not particularly good or cheap. You can do much better driving.
