Whats sad is Norway sits right next to the country which manufactures Scania and Volvo Busses, but instead buys busses from thousands of km away. I suppose cost is all that maters these days, even for national infrastructure which must remain in control and secure.
I know for a fact that at least one of those companies also installs SIM cards in all their busses.
The only difference is who could potentially use the backdoor, and yes Sweden seems slightly less poised to attack Norway than China. At least these days. Because, let's face it, the Swedes owned Norway back in the day and them wanting their oil-rich lucky cousin back at home is deranged but not as much as the Chinese wanting the fjords....
