"quantum compass technology"
Dear oh dear, what politicians won't do to make it look like they're doing something about something. Quantum compass technology, really. A cubic-meter sized contraption that uses lasers to super-cool atoms in order to detect movement in a single plane. That could conceivably be useful for a car, which generally only moves in one direction at a time, but I seriously doubt that a Twingo will have either the space or the power output to sustain laser-operated super-cooling just to get from place to place.
And £95 million for a report ? Sounds like the guy who typed that up can retire right now.
A UK-specific GPS system ? I honestly think you have better things to do at this time with what is left of your money. Besides, GPS units that work with the US and EU constellations will soon be available for £99.99, no subscription required. So why are you spending money you don't have on this pipe dream ?
