Impeller may expand and deform under the influence of fuel, and interfere with the shell of low-pressure fuel pump, resulting in poor operation of low-pressure fuel pump. In extreme cases, the vehicle may not start normally, or the engine may turn off during driving, which may cause safety hazards.

Learn to use Tesla model? X test discovery model? X's Autopilot recognized the stop sign in the advertisement and stopped the car automatically. In addition, the research team also tested Mobileye's car in the parking lot and found that the problem of embedding traffic signs in identification advertisements also appeared in the car system.

Researchers say that the automatic identification system of cars is easily attacked by hackers, and hackers are likely to invade highway advertising signs to operate, thus causing traffic chaos and accidents.
