The surfaces the car can drive on varies by the car type and design. Most have little to no issue driving on smooth indoor surfaces or asphalt. But, when it comes to any “off-road” conditions, it varies specifically by car. Look for a higher-end 4WD remote control care if you want to drive it on rough terrain, like grass and dirt. Be sure to know where you plan on driving the car, and pick a model that matches your needs.
