On October 23, 2024, Li Auto's intelligent driving end-to-end + VLM started a full push. The most attractive thing about the upgraded version 6.4 this time is the dual-system intelligent driving solution. Fortunately, on the same day, Li Auto sent me the MEGA test drive car. Can the 6.4 version of the system be fully utilized on the 5.35-meter-long MPV?
