The smallest Mercedes-Benz car, the Smart, can be driven on highways. Here are some precautions for highway driving: 1. Maintenance: Before driving on the highway, you should conduct a comprehensive inspection of your car, especially the tire pressure and brake discs. Additionally, check the engine before entering the highway, and it's best to perform a car maintenance service. 2. Safety: Always prioritize your safety. Be cautious while driving and try to avoid large trucks, especially those carrying cargo, as they can obstruct your view and make it difficult to assess the situation. 3. Habits: Develop good safety habits. Always remember to wear your seatbelt because sudden braking on the highway can cause you to be thrown forward due to the car's inertia if you're not wearing one.

I've been driving a Mercedes-Benz Smart for several years, often using it on highways to travel to neighboring cities for business. Although the car is small in size, it maintains a stable speed on the highway and can easily sustain 120 km/h. The engine responds well, making the drive smooth, with a fuel consumption of about 5.5L/100km, which is much more economical than larger cars. However, because the car is light, it feels a bit shaky in strong winds, and you need to hold the steering wheel tighter. I've taken it on a few long trips, and it's fine for one or two hours, but comfort decreases beyond that distance, and the cabin space is small with limited luggage capacity. Safety systems like ABS and stability control have been helpful in avoiding accidents. It's advisable to regularly check the tires and suspension to ensure they're in good condition. Highway driving is no problem, but it's more suitable as a daily commuter rather than for family road trips.

I prioritize fuel efficiency in a car, and I chose the Smart partly because it's economical even at high speeds. When cruising at 120 km/h, the engine operates efficiently, averaging 6L/100km, which saves a significant amount of money in the long run. Maintenance is straightforward, and parts are easy to find, but high-speed driving increases engine load, requiring monthly checks on oil levels and tire pressure. The car's small size makes lane changes on the highway nimble, though you need to be cautious of the wind suction effect near larger vehicles. I often use it for short business trips, as it's suitable for about an hour's drive, with space just right for a single person and small packages. While I'm not a speed enthusiast, it meets highway demands well—practical and affordable.

As a cautious driver, I believe the Smart can handle highways but requires extra care. Small cars have poorer stability at high speeds and are prone to drifting in strong winds. Safety features like airbags and stability control help mitigate risks. I always maintain a speed of 100-110 km/h to avoid bumpiness. Avoid highway driving during rain or fog as wet roads increase skidding risks. Replace aging tires promptly with high-speed tires. It can drive normally, but requires focused steering and sufficient following distance. I perform daily checks to ensure safety.
