20 19 65438+ 10/2 A tragic unilateral traffic accident occurred in Zhengzhou, Henan Province: a Lincoln pilot test drive car rushed into the green belt in the middle of the road and hit a big tree, causing one death and four injuries on the spot, which instantly made headlines.
Cases of car accidents caused by improper operation of test drivers have long been common, even in the automobile media circle where vehicle cognition and driving level are generally higher than that of the public, similar incidents occur from time to time. This can not help but lead to some deep thoughts on the test drive.
What conditions are most likely to cause accidents during the test drive?
1, because the car-does not understand the characteristics of the test drive vehicle+drives blindly.
Bian Xiao thinks this is the first reason. As we all know, the displacement, power adjustment, driving form and control characteristics of each brand and model are different. For example, the dynamic characteristics of front-wheel drive and rear-wheel drive are completely different, one is easy to push the head (understeer) and the other is easy to flick the tail (oversteer); Some cars have sensitive throttle adjustment in the initial stage, while others are in the middle and late stage. Especially for the models with large-displacement turbocharged and high-speed power output, the powerful power suddenly jetted out during fierce driving can easily make the test drivers who just started to contact this car feel adrenaline surge and nervous.
Just like the Lincoln full-size SUV pilot tested by Wang in this case, its 3.5T? The powertrain of V6 turbocharged engine+10AT gearbox can generate 387 horsepower and 680 Nm of surging power at the maximum, and the speed increase is quite rapid. However, its vehicle weight of nearly three tons leads to great driving inertia, which makes its emergency braking avoidance response speed much lower than that of small and medium-sized vehicles at medium and high speeds. From the analysis of accident scene photos, it is conservatively estimated that the impact speed is above 70/km. (All A-pillars are deformed by extrusion)
Therefore, no matter how skilled you think you are in driving, you must get used to driving an unfamiliar car step by step. Even if it is a "dream car", don't get too excited during the test drive and relax your vigilance.
If you are not completely sure about driving, don't just seek speed. It is very naive to "show off your driving skills" with speed, which will eventually lead to tragedy and regret.
2. Because people-drivers have poor skills.
If you go to a shop in 4S for a test drive now, the test drive expert may ask you a question: How long have you been driving? Bian Xiao once had a brief talk with him about this, and found that the reason why he asked this question was because many "novices" who just got their driver's licenses were very lacking in driving experience, and it was easy to be careless during the test drive, and even made some dangerous operations (for example, merging without turning on the light and looking at the rearview mirror, merging without confirming the distance between cars, and accelerating with a large throttle has no concept of speed, etc.). ), easily lead to all kinds of traffic accidents.
A series of personal injuries/economic losses caused by reckless driving are not only borne by the test driver himself, but also the daily sales of 4S shops will be seriously affected by the maintenance and suspension of the test drive. (Delaying the normal test drive experience of other consumers)
In fact, in some developed countries, such as Germany and Japan, the driver's license grading system has been widely implemented. Take Japanese motorcycle driver's license as an example, there are four grades from small displacement below 50cc to large displacement above 400cc. Driving without advanced qualification will be regarded as driving without a license. In principle, novices should take turns to take the exam.
This move is undoubtedly very helpful for new drivers to clearly and gradually cultivate a solid sense of car, which greatly reduces the probability of car accidents caused by the serious discrepancy between personal driving skills and the models they drive.
Of course, this is also of great reference significance to the reform of automobile driving test in China.
What are the precautions for test drive?
Bian Xiao summed up the following points based on the previous experience of in-store test drive:
1. Before you go to the store for a test drive, you should know as much as possible about the reserved test drive model. Professional media evaluation can give you a specific understanding of vehicle characteristics. Be mentally prepared in advance.
2. Before starting the test drive, listen carefully to the safety precautions and test drive route informed by the test drive specialist, and conduct the test drive experience as required. Usually, the test drive agreement will indicate the test drive route, the test drive duration (usually one lap) and the claim commitment after the traffic accident. If we deviate from the prescribed route or temporarily test drive, then all the safety problems arising therefrom will be borne by us.
3. Fasten the seat belt before the test drive, and adjust the inside and outside rearview mirrors and seats to a proper position (especially the front, back and height):
Seat fore-and-aft adjustment
Upper body: Don't be too far/too close to the steering wheel. When both hands hold the steering wheel at three o'clock or nine o'clock, elbow bending 120 degrees is the best, which can ensure that the arm has enough space to make the evasive action of turning the steering wheel greatly, and at the same time, the exertion of strength is more relaxed and efficient.
Verification method: the body is attached to the seat back, and the wrist can just be placed on the upper edge of the steering wheel when the hand is straightened forward.
Lower body: Make sure that the knee still bends (about 120 degrees) after fully stepping on the brake pedal, so as to ensure that the right leg can be flexibly switched between the accelerator and the brake pedal.
Seat height adjustment
Proper seat height can ensure that we can get a wide field of vision while driving. There should be more than one punch in the head space. If it is too low, the steering wheel will block the line of sight and instrument, and the blind area near the A-pillar will also become larger.
Finally, I hope that after reading this issue, you can be cautious, don't be nervous and don't be careless in the future driving process. You know, behind everyone is a family. (Auto Review/Low Frequency)
