It almost feels like government does something when it is pushed. Either financially, by donors and lobbyists, or public pressure before election for votes.
Since no such pressure exists, government is not likely to do anything.
As well as a technology thats going to cut deaths by ~30K-40K/year, not to mention several times that in injuries.
Its a double-edged sword though. Self-driving (electric) cars equals almost no need for insurance companies, body shops, etc.
More broadly, its important we start looking at quality of life as a KPI instead of GDP. Technology makes us more efficient, it doesn't make us consume more.

if you add the DoD as a major customer - the original Grand Challenges had very clear "truck on the desert road" smell for a reason :) - the life saving effect will be even bigger (at least if we count US/Western lives)
