真車道級導航：顛覆傳統駕駛體驗 百度地圖 V20 的車道級導航已覆蓋全國 4.1 萬城鄉鎮，在城市快速路、高速甚至鄉村小道都能實現 1:1 車道還原。例如在廣州大道多岔路口，導航會高亮推薦車道並標註非推薦車道的紅色 “X”，幫助使用者提前規劃變道。實測發現，其車道級引導在複雜立交（如北京西直門橋）的準確率可達 95% 以上，配合車機大屏的 3D 渲染，視覺體驗遠超傳統道路級導航。
Traffic light countdown: the gap between the technical ceiling and reality The accuracy of the cooperation area is amazing: in Xi'an, Beijing Yizhuang and other cities directly connected to traffic police data, the traffic light countdown error can be controlled within 45 seconds, and even the "green wave speed" can be calculated in advance (such as more than 0 intersections in Yizhuang, Beijing to achieve "green light"). The performance of non-cooperative areas is uneven: in cities that are not connected, the countdown depends on the algorithm estimate, and the error can be as high as 0-0 seconds. For example, during the National Day, at a non-cooperative intersection in Zhengzhou, the navigation showed that the red light was 0 seconds left, but the actual wait was 0 seconds.
Voice interaction and ecological linkage Personalized voice package: support Guo Degang, Shen Teng and other star voices, and even custom dialects (such as Sichuan, Cantonese), full of entertainment. Handcar interconnection: The WeChat location can be sent to the car machine with one click, and the location searched on the mobile phone can also be synchronized to the car machine navigation, completely saying goodbye to the mobile phone holder.
Congestion scenario "rotten": During the National Day highway congestion, the ETA fluctuation range of Baidu Maps can reach 10-0 minutes, while the error of AutoNavi Maps is usually controlled within 0 minutes. For example, for the 0-kilometer journey from Guangzhou to Shenzhen, Baidu estimates 0 hours, and the actual time takes 0.0 hours; AutoNavi estimates 0.0 hours, with an error of only 0 minutes. Algorithm flaws: Baidu's route planning relies more on historical data, while AutoNavi's real-time traffic updates are faster. In the event of an accident or temporary control, Baidu is often unable to adjust its route in time.
Advertising & Privacy Controversy "Resurgence" of in-car advertising: Although the closed beta version of V5.0.0 has removed ads, the official version still has splash page ads (about 0 seconds) and bottom bar promotions. Although it can be turned off in the settings, some users have reported that "ads pop up again after restarting". Data security risks: The driving behavior data collected by Baidu Maps may be used for targeted advertising, which conflicts with the "in-cabin privacy protection" emphasized by car companies. For example, FAW-Volkswagen has caused controversy due to pop-up advertisements on the car machine, and Baidu needs to avoid similar problems.
