Can Tesla Drive Autonomously?

What is the reason for the buzzing sound at 120 km/h?

The reasons for the buzzing sound at 120 km/h are as follows: 1. Excessive tire pressure: When using the car, the tire pressure should be adjusted within the standard range (usually 2.3bar-2.5bar). If the tire pressure is too high, it will cause severe wear on the tire tread, reduce the tire's shock absorption performance, and make the tire noise more noticeable. 2. Abnormal tire wear: The tire tread comes into contact and friction with the ground. If the tread wears unevenly and has bumps, it will produce a buzzing sound. 3. Damaged wheel hub bearing: Worn wheel hub bearings will cause a buzzing sound due to long-term use leading to wear and looseness. To protect the wheel hub bearings, avoid violent impacts on the wheels and prolonged driving through water during normal use.

How to Drive Through Waterlogged Roads in Rainy Weather?

Here are the techniques for driving through waterlogged roads in rainy weather: 1. When encountering water accumulation on the road while driving: Slow down or stop to observe. If the water level reaches two-thirds of the bumper or tire height, proceeding further poses certain risks. High speed increases the actual water depth the car passes through, potentially allowing water to enter the cabin from the engine compartment or chassis. Avoid driving against waves created by large vehicles. If the water level is high, try to detour instead of forcing your way through. 2. While driving through water, besides maintaining a low speed: Try not to stop, shift gears, release the throttle, or accelerate. Instead, drive at a steady speed with low gear and moderate throttle. Avoid speeding through, which can create large waves or splashes. 3. If the car stalls in water, do not attempt to restart it immediately: Take measures to tow the car to a safe location with less water as soon as possible. Serious water ingress into the engine can occur if water enters through the air filter into the intake valve and then into the cylinder via the intake pipe. Do not try to restart the engine, as this may cause deformation of critical components like the crankshaft and connecting rods, leading to engine vibration or even component breakage. Stalling in water likely means the engine has taken in water; after stalling, only tow the car in neutral to a repair shop for cleanup. 4. After driving through water, promptly remove moisture from the brake pads: Drive at low speed while lightly pressing the throttle and gently applying the brakes. For those who can't multitask, repeatedly apply the brakes several times at slow speed to generate friction heat between the brake drum and pads, evaporating the moisture.

Do leather car seats still need seat covers?

It is not recommended to use seat covers on genuine leather seats. The reasons are as follows: 1. Easy maintenance and long service life: The purpose of using seat covers is to extend the service life of leather seats. With proper care during daily use, leather seats can last 5-8 years. Cleaning leather seats is relatively simple - ordinary dust and stains can be removed by gently wiping with a clean cloth. From this perspective, leather seats are easier to maintain than regular fabric seats. 2. Safety considerations: From a safety standpoint, it's also not advisable to use seat covers on leather seats as they may interfere with the deployment of side airbags. In emergency situations requiring airbag deployment, the added seat covers could prevent the airbags from fully opening, compromising driving safety.

How many points will be deducted for one violation of traffic regulations?

Failing to yield as required will result in a deduction of 3 points. If a motor vehicle driver commits any of the following violations, 3 points will be deducted for each offense: 1. Illegally towing a broken-down or accident-involved vehicle on the highway. 2. Carrying passengers in the cargo compartment of a freight vehicle or on a two-wheeled motorcycle on the highway. 3. Riding or straddling the lane demarcation line on the highway. 4. Driving on the highway in low visibility weather conditions without following regulations. 5. Driving a motor vehicle prohibited from entering the highway onto the highway. 6. Failing to use lights and set up warning signs as required after a vehicle breaks down or is involved in an accident on the road.

Which is more fuel-efficient, 1.6T or 2.0L?

When driving on urban roads, the 1.6T is slightly more fuel-efficient than the 2.0L, but the difference in fuel consumption between the two is minimal during high-speed driving. Here are some related details: 1. In city traffic congestion, turbocharged models with smaller displacements are certainly more fuel-efficient than naturally aspirated ones. However, once on the highway where the same power output is required, the fuel consumption will be similar when considering only the engine and ignoring other external factors. Turbocharged engines can be more fuel-efficient to some extent because they reduce pumping losses, allowing for direct air intake. Simply put, this means reducing the power wasted during the process of the cylinder descending and drawing in air. 2. The maximum power and torque of a 2.0L naturally aspirated engine are similar to those of a 1.6T turbocharged engine. The 2.0L naturally aspirated engine lacks the abrupt sensation of turbocharging, providing linear acceleration. It generally accelerates faster than the 1.6T from a standstill, but on the highway, the turbocharged engine still delivers better power. Naturally aspirated engines have more mature technology and lower failure rates compared to turbocharged engines. If the car's body is not very heavy, the 2.0L naturally aspirated engine outperforms the 1.6T and 2.0T in terms of control, fuel efficiency, and failure rate, with lower repair and maintenance costs.

What to Do When the Car Door is Frozen and Won't Open?

Here are the methods to deal with a frozen car door that won't open: 1. If the door is frozen: Pour hot water on the frozen area. After opening the door, immediately wipe off all residual water to prevent thicker ice from forming in the door gaps. 2. If the lock is frozen: Use a hairdryer to blow hot air directly into the lock cylinder, or heat the car key with a lighter and gently insert the hot key into the lock. The ice in the lock will melt upon contact with the high temperature. 3. If the windows or windshield are frozen: Warm up the car, remove the snow from the body and glass, and after the engine warms up, turn on the heater and set it to defrost the front windshield until the snow melts. Additional tips for winter car care: 1. Maintain the battery promptly in winter. Battery discharge is the most common issue during this season, so checking the battery level is crucial. If white oxides are found on the electrode terminals, rinse them off with warm water, as these oxides can cause insufficient charging, leading to a discharged battery. In severe cases, this may prevent the car from starting or even render the battery unusable. 2. Replace the windshield washer fluid with a winter-grade one in time. As winter approaches and temperatures drop, especially in northern regions where temperatures can fall below zero degrees Celsius, it's essential to switch to an antifreeze windshield washer fluid. Ensure the antifreeze fluid's freezing point is lower than the lowest temperature in your area to prevent the washer fluid reservoir and pipes from freezing and cracking.
