The complaint cites two executives as describing the interface as a "dark pattern" exhibiting "very questionable design decisions."

Still, Joe Ten Eyck, who coordinates wildfire and urban interface programs for the International Assn. of Firefighters, said extreme weather conditions can make brush clearance even more important.

When catastrophic fires occur, experts often blame the so-called wildland-urban interface, the vulnerable region on the perimeter of cities and suburbs where an abundance of vegetation in rugged terrain is susceptible to burning.

“The urban interface is changing and we’ve designed for classic fires, not a wildfire blowing through a community,” Adams said.
