How fast can you drive? 80km/h? 160km/h? Does speed matter? To a certain extent, speed does matter if you're in a hurry to reach your destination. On a freeway, you could drive 160km/h or more though the speed limit is a mere 110 km/h in our country. You'll still arrive in one piece provided your car tires and engine are in top condition, and your driving skills is 9 out of 10.
However, not everyone is able to handle that kind of adrenaline rush. This does not make them a sissy. I believe there are many tortoises out there who are careful drivers, and they're slow because they want to be safe, and they want their passengers and other drivers on the road to be safe too. On the other hand, driving at a snail's pace on a freeway is a bit too much because freeways are not built for extremely slow drivers.
People drive super fast because they like the thrill of having the adrenaline pumping through their heads and feeling good when they arrive at their destination. Others don't want the thrill, but the enjoyment of cruising along at a constant speed. If you're in a hurry, well... drive a little faster but just be sure that you're careful.
If a driver drives slow and you push them to go faster, chances are, you might not arrive your destination in one piece. Slow or fast, drive safely - that's what matters most.
