TROY, Mich.—Despite US dominance in so many different areas of technology, we're sadly somewhat of a backwater when it comes to car headlamps. It's been this way for many decades, a result of restrictive federal vehicle regulations that get updated rarely. The latest lights to try to work their way through red tape and onto the road are active-matrix LED lamps, which can shape their beams to avoid blinding oncoming drivers.
From the 1960s, Federal Motor Vehicle Safety Standards allowed for only sealed high- and low-beam headlamps, and as a result, automakers like Mercedes-Benz would sell cars with less capable lighting in North America than it offered to European customers.
A decade ago, this was still the case. In 2014, Audi tried unsuccessfully to bring its new laser high-beam technology to US roads. Developed in the racing crucible that is the 24 Hours of Le Mans, the laser lights illuminate much farther down the road than the high beams of the time, but in this case, the lighting tech had to satisfy both the National Highway Traffic Safety Administration and the Food and Drug Administration, which has regulatory oversight for any laser products.
The good news is that by 2019, laser high beams were finally an available option on US roads, albeit once the power got turned down to reduce their range.

This comment is getting downvoted, and I don't oppose nuclear, but I do think it's worth noting that the nuclear energy sector has still under-priced the costs of nuclear waste management, transportation, and storage. Engineers don't have practical methods of building storage containers and buildings that can last as long as the half-life of nuclear waste (1,000-10,000 year), and the long tail of storage costs has not been priced into the cost. Typically, this does end up being paid for by taxpayers over the course of many years. No energy generation system is without downsides, but it's worth acknowledging them.
