Car view is a button for switching the display of data such as mileage. Here are some introductions about the multifunctional buttons of the car: 1. The multifunctional buttons on the steering wheel are usually for the convenience of the driver to operate volume adjustment and menu selection, etc. Some models with car phones will also set the call and microphone buttons on the steering wheel. 2. The multifunctional steering wheel includes audio control, air conditioning adjustment, car phone, etc., and some also set the cruise control button on the steering wheel. 3. The driver can directly operate many electronic devices in the car on the steering wheel without having to look for various buttons on the central console, which allows them to focus more on the road ahead and greatly improves driving safety.

Last time when accompanying a friend to choose a car, the salesperson explained the meaning of 'view' in vehicle configurations, which mainly relates to driving visibility. When buying a car, it's essential to pay special attention to elements affecting visibility such as the windshield angle, the thickness of A-pillars, and the coverage of rearview mirrors. For example, SUVs offer a higher seating position for a farther view but are prone to visual blind spots, while sports cars with streamlined designs often compromise side and rear visibility. Many cars now come equipped with 360-degree panoramic imaging systems, projecting real-time images from body cameras onto the central display screen, which is particularly useful when reversing. To truly experience the differences in visibility, it's recommended to observe the coverage of rearview mirrors during test drives on various road sections, especially checking if surrounding vehicles can be clearly seen during lane changes and turns. After all, good visibility is directly related to driving safety.

I deeply realized this when driving my dad's old off-road vehicle on mountain roads. After rain, the rearview mirrors were completely fogged up and basically became decorations. Vehicle visibility isn't just about the numbers in the manual - when you turn on fog lights in rainy weather, the lighting range affects your judgment of obstacles. New drivers should pay special attention to the visibility height of the interior rearview mirror. If the seat is adjusted too high, it blocks the lower half of the rear window; if too low, you can't clearly see the road conditions ahead. I remember once driving my friend's new car - her side windows with dark tint film made it impossible to see electric bikes when turning at night, almost causing an accident. Ultimately, after buying a car, you need to actually experience where the blind spots are from various angles to drive safely.

The bird's-eye view system frequently mentioned in new car models nowadays essentially utilizes multiple wide-angle cameras at the front, middle, and rear to create a panoramic view. This real-time stitched image can effectively reduce blind spots. Last time when helping a colleague park, I noticed his car even featured a transparent chassis display function. However, practical use requires attention to image distortion issues, and camera lenses getting muddy in rain can severely affect display quality. Some luxury cars' windshield projection systems can display instrument information directly in the driver's line of sight, theoretically making it safer by eliminating the need to look down at the dashboard. But all such electronic visual aids should be used in conjunction with physical rearview mirrors for reliable operation.

Over the years of working with used cars, I've inspected tens of thousands of vehicles, and visibility checks are an essential part of the process. When purchasing a car, I deliberately simulate a short driver's seating position to test whether traffic lights 50 meters away can be seen above the rear window ledge. Accident vehicles often have distorted sightlines after A-pillar repairs, requiring laser rangefinders to compare left and right blind spot symmetry. Last year, a flood-damaged car seemed fine at first glance, but later I discovered its heated mirror function had failed - the rearview mirror turned frosted like ground glass in rainy conditions. My advice for used car buyers: bring a reflective traffic cone to test reversing visibility by placing it behind the vehicle. This provides far more tangible proof of blind spot size than any salesperson's claims.
