america's train system is in piss poor shape i think. our railroad technology is at least 50 years out of date. wouldnt mind taking a train if it saved me a few hundred bucks for a ticket. buses arent bad either if you want to travel on the budget. but being in alaska, its hard enough to get them to build roads and tracks. the only ground connection we have with the rest of the usa is the treacherous one lane highway through canada, which was built during ww2 and probibly not maintained much since.
a hardware solution is desirable i think. software firewalls is just crazy talk. on the other hand why even bother giving passengers entertainment systems and internet access. id rather they focus on making the ride cheaper. onboard entertainment systems have caused at least one plane crash that i know of, where wires arced and caused a fire, which destroyed the plane. why add further complexity to an already complex aircraft. people just seem to be more concerned with alleviating boredom they they are with safety.
