In theory, yes, a car can be driven for 24 hours straight, but it's not exactly a walk in the park. The ability to do this depends largely on the vehicle's condition, driver endurance and road conditions. However, prolonged driving can cause significant wear and tear on your vehicle and is generally not recommended. Moreover, it's crucial to consider safety aspects as driving for such a long period can lead to fatigue and compromised attention. So, while it's possible, it's essential to take regular breaks to rest, refuel and maintain safety.
