Eventually. It's currently illegal in the US because of your ancient FMVSS that requires high beams to be either on or off and nothing in between. However, NHTSA (along with several manufacturers) are pushing for a change.
They look terrible. I thought nothing could be worse than the BladeScan adaptive lights on my Lexus RX but I was wrong. My wife’s Mazda CX-30s adaptive lights on the other hand are astonishing. They light way down the carriageway and right up to the tops of trees and into the fields. You literally are driving through a large, tree-height, box of daylight and she only has a single lens per side of vehicle. My Lexus has 4 light units per side.
I will definitely need to test drive the EV6 at night on rural roads in North Yorkshire, UK before placing an order. Bad lights, for me, would be a dealbreaker.
