It's obvious what's going on here. Solar flare activity has been increasing ever since mankind developed radio technology. Obviously we're polluting the solar system's electromagnetic climate, and we must be stopped!

Sorry I'm late. Bit of a bugger on the way to work - solar flares interfered with the GPS.'

But it does offer a (literal) get-out-of-jail-free card for the MoD when it comes to explain why our boats ended up in Iranian waters.

So when all our cars are locked down with Pay-as-Drive (tracking) systems, and our cars won't start because the GPS network is floored. Then what are we supposed to do? Sit on the drive and admire the dash-panel?
