Excellent! So you think a GPS enhancement that just covers the UK adds value? Who are you planning on bombing with this increased accuracy?
"It looks like the industry is trying to make self-driving cars the next tech unicorn" ......
And for them to work they can't rely on super high GPS positional accuracy otherwise they will all crash under the first bridge they encounter. GPS is need to give them a rough position on there map, after that they are on their own and need to rely on their onboard sensors. Increasing your map relative positional accuracy from 2m to 1.5m has little tangible value.
