BMW announced a new addition to its luxury cars: road warmers. Pivoting convex lasers mounted in front of each wheel would melt ice and snow on the road as the car was being driven. Turbo fans would then remove excess moisture from the road. According to BMW's press release, this invention would "virtually eliminate the need to clear your driveway during winter." The advertisement assured readers that road warmers would eventually become standard on all new BMWs, but until then dealers would install them on older models free of charge.
