What is an Automotive OTA Upgrade System?

Which is faster at starting, manual transmission or automatic transmission?

Manual transmission starts faster. The transmission efficiency of manual transmission can generally reach over 90%, while that of automatic transmission is usually only between 70% to 80%. In a manual transmission car, the connection between the drive shaft and the clutch during driving is purely mechanical, without interference from electronic systems. In contrast, the connection in an automatic transmission car is controlled by electronic devices. To prevent the engine from operating under high load, automatic transmissions generally control the output to be gentle. Manual transmission, also known as a manual gearbox, requires the driver to manually shift the gear lever to change the gear meshing device inside the transmission, thereby altering the gear ratio to achieve the purpose of shifting. Automatic transmission usually refers to the car's automatic gear-shifting mechanism, where the control system of the automatic transmission selects the appropriate gear automatically based on the engine's speed and load during driving.

Why Shouldn't You Keep Bottled Water in the Car?

Keeping bottled water in the car can pose safety hazards. Generally, bottled water has an expiration period, typically one year for bottled mineral water. Bottled mineral water does not contain chlorine and lacks antibacterial properties. In the high temperatures of summer, it can take just a few hours for bacteria to multiply significantly. More details about keeping bottled water in the car are as follows: 1. Impact of high temperatures: When the trunk temperature exceeds 70°C, it can easily cause the one-year shelf life of bottled water to end prematurely. Normally, one cubic meter of air contains about 5,000 bacteria (not pathogenic bacteria), and over time, these bacteria can multiply and affect drinking water hygiene. Generally, opened bottled water will have bacteria levels exceeding safe limits after more than 48 hours. When temperatures exceed 70°C, the plastic bottle softens, making it easier for oxygen to penetrate the bottle and causing the water's shelf life to end prematurely. 2. Impact of sunlight: If bottled water is placed in direct sunlight inside the car, it can easily lead to an explosion. When sunlight passes through the car window and directly hits the bottle, the bottle acts like a convex lens, focusing the light. Combined with the already high temperature inside the car (around 70°C), the focused light spot from the bottle can reach temperatures of over 120°C, which can easily ignite other flammable materials and indirectly cause an explosion.

Are all questions in Subject 1 single-choice?

Not all questions in the Subject 1 exam are single-choice. The test for driver's license Subject 1 consists of 100 questions, including single-choice and true/false questions. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," each question is worth 1 point, totaling 100 points. If a candidate answers 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1, also known as the theoretical exam or driver's theory test, is part of the motor vehicle driver's license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is conducted on a computer with a time limit of 45 minutes. Subject 1 exam content: Driver's license and motor vehicle management regulations; road traffic conditions and rules; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 exam precautions: Candidates should dress appropriately for the exam; no slippers are allowed. Electronic devices and bags are not permitted in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen before entering the exam room, and store personal belongings in lockers. Upon entering the exam room, candidates will be assigned seats at the identity verification station. Once seated, the exam begins. Ensure the camera is aligned correctly and follow exam discipline. If you fail the first attempt, a retake is available on the same day. Failing the retake requires payment to reschedule. After the exam, queue to collect and sign the score report; unsigned reports are invalid. There is no limit to the number of times you can schedule the Subject 1 exam. Each subject can be taken once, with one retake allowed if you fail. If you do not take the retake or fail it, the exam process ends, and you must reschedule. In contrast, Subject 2 and Subject 3 allow only five exam attempts, with scheduling available ten days later. If you fail the Subject 3 safe and civilized driving knowledge test, the passed road driving skills test scores remain valid. The driver's license test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official terminology (as per the Ministry of Public Security's Order No. 123) does not include the term "Subject 4."

What to Do If You Haven't Driven for a Year After Getting Your License?

Start by practicing with an automatic transmission car, as it's simpler to operate than a manual transmission. Many people buy a used car to practice after getting their license, as used cars are relatively inexpensive. If you still remember the basic driving operations but feel nervous after not driving for a long time, you can ask an experienced driver to sit in the passenger seat. Skills can be honed over time, but courage must be mustered on your own—especially when coordinating the accelerator, clutch, and brakes.

What is the reason for the continuous restart of the dash cam?

Dash cam continuously restarting is due to battery failure, and replacing the battery can solve the issue. Dash cams are mainly divided into two categories: portable dash cams and aftermarket integrated DVD dash cams. Portable dash cams can be further divided into rearview mirror dash cams and data dash cams, which are characterized by good concealment and easy installation. Aftermarket integrated DVD dash cams are usually vehicle-specific and can be divided into front-mounted and rear-mounted types. The modification difficulty for installing this type of dash cam is relatively high, but it can maintain the aesthetics of the car interior after installation.

What are the effects of not completely draining the engine oil?

The effects of not completely draining the engine oil are: reduced engine efficiency. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in base oil, mainly containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. The main functions of engine oil are to reduce friction and wear on moving parts, remove sludge (one function of dispersants) and varnish (detergents) from the engine, neutralize acids produced by fuel and lubricant oxidation (detergents), improve piston ring sealing, and cool the engine by carrying away heat from moving parts.
