I'm being somewhat facetious, but there are several ways to fund local governments, including but not limited to:
A. Tax the people directly based on $ASSET (usually income, or property, or a combination of the two). B. Lower direct taxes as well as state and federal grants, and fines from enforcement.
As someone who doesn't necessarily mind sending a few dimes on the dollar to the government, and doesn't speed often enough or at such egregious speeds that I'm subject to hyperbolic "highway shakedowns," I kind of prefer B to A because it results in a lower effective tax rate for me.
In Sweden this extra tax provides free schooling up to and including university (you even get paid going to higher education US$300+/month in grants), low cost health care with a cost ceiling (US$130/year), affordable child care, social security net, local government owned and (well) managed infrastructure (power, water, fibre, roads, etc.)
Our local government is funded through direct taxation. My local government tax rate is 30.2%.
Not sure it tells the whole story though. VAT is not included in effective tax rate AFAIK (as defined in the Economist article).

Also note, it doesn't have to be a "government" thing, where you'd expect some protection (at least on paper). It can be a completely private affair between the car makers and insurnace companies.
In fact it is already almost there and it is called CLUE ( https://www.privacyrights.org/clue-and-you-how-insurers-size... ) -- a database used by insurance companies to evaluate indivicuals and record the claims they've made in the past. Feed info from these self-driving cars into them and you can't even claim any privacy or constitutional rights were violated.
I've long wondered why the toll authority does not simply do the math on entry and exit and send citations to the top 5-10% of speeders. It's generate many thousands of dollars in revenue for sure.
Maybe it's time to split up societies? Some people seem to value absolute freedom to do anything (and freedom from consequences). Others prefer having things actually work and be nice for everyone.
