Seems like the obvious solution to this, is if you collect driving data on public highways, the data has to be made available to the public. If you collect the data on private highways you are free to keep it private. If you don't intend to use it in a product on public highways it can remain private.

Doesn't even seem that crazy when you consider the government is already licensing them to be able to use their private data anyway. Biggest issue is someone didn't set it up this way from the start.
