When a car's range display shows zero, it may still be able to travel 30-50km. Considerations when buying an electric vehicle: 1. Car model: This is not much different from buying a fuel-powered car. Consumers need to choose a model that suits their needs. Larger vehicles may consume more electricity. If it's just for city commuting, a micro electric vehicle can be chosen, while compact electric sedans are suitable for family use. Make a reasonable purchase based on the owner's requirements. 2. Vehicle range: The reason electric vehicles have not yet become widespread is largely due to range limitations affecting their development. Therefore, it's essential to understand the range of an electric vehicle when purchasing to avoid running out of power during daily driving. 3. Charging time: Charging time directly affects the usability of the car. Electric vehicles take a relatively long time to charge, and running out of power in an emergency can be very troublesome. Hence, the length of charging time is also a factor to consider when buying an electric vehicle. If the charging time is long, consumers are advised to think carefully before making a purchase.

That time when my car showed 0 range, I still thought I could push it to the gas station, but it stalled on the side of the road after driving less than 10 km, almost making me miss an important meeting. Since then, I've learned that car manufacturers design a buffer zone—gas cars have sediment fuel at the bottom of the tank, and EVs reserve the last 5% of battery, theoretically allowing 5-15 km of range, but real-world tests vary greatly due to road conditions and driving habits. Especially on mountain roads or rainy days, the risk is higher. Stalling could also damage the fuel pump or battery, with repair costs far exceeding the money saved on fuel. I recommend developing the habit of refueling or charging early to avoid waiting until the numbers hit zero. I installed a reminder app on my phone that alerts me when fuel drops to half or battery reaches 30%, making driving more worry-free and effortless.

As a car enthusiast who treasures my vehicle like life itself, I've discovered that a range display of 0 is actually deceiving—your car might still have a tiny emergency reserve. For example, fuel-powered vehicles often have estimation errors in remaining fuel levels, with manufacturers hiding about 10km worth of reserve in the tank corners; electric vehicles maintain a buffer through intelligent systems, giving you a final 5-10km cushion. But don't rely too much on this—I've experienced driving until the end only for the car to suddenly shut down, even causing engine overheating or battery damage. My advice is to always check your fuel or battery gauge before each trip and set a safety threshold, like refueling/recharging at 20%; if you see 0 displayed, don't push your luck—stopping to call for help is infinitely better than breaking down. Remember, driving on empty isn't a life-threatening challenge—it's a money-burning hazard.

Driving until the range hits zero is asking for trouble and poses significant risks. I've seen accident cases where people pushed for a few more minutes on the road, only for their car to break down on the highway, leading to dangerous rear-end collisions. Vehicles are designed with a buffer of 5-15 km, but the margin of error is large and unpredictable. Running out of fuel can burn out the fuel pump, while deep discharging an electric vehicle's battery causes permanent damage; the repair costs are severe. Safety first—stop when you should, turn on the hazard lights, and wait for assistance.

After years of driving lessons, I've learned to respond promptly to low-range warnings. When the car shows 0, it can still barely run a short distance, such as up to 20km for fuel vehicles and within 10km for electric vehicles; but don't test your luck, as running out of fuel or electricity can cause the engine to seize, significantly reduce battery life, and double repair costs. I always set reminders to refuel or recharge when the level is halfway, saving both hassle and money. Developing a habit of regular maintenance helps avoid the tragedy of running out.
