Before I learn drive, I always imagine that driving make people happy, driver must feel happiness with that. They can turn the steering to right or left and look "cool".
After I learn it, I realize that there are someone take you sometime is good too, i feel the happiness of being passenger also. Drive is such a energy consume activity, especially at KL and long distance drive.
We can take a rest inside the car, looking at the beautiful screen around, eating with the "free" hands and so on.
The fact is that we can be happy either being a driver or passenger (what about the walker? ha, not relevant), it is just different kind of happiness. Would you like to be a driver or just passenger sitting on the car? No matter, you which you are, please do remember you are in happiness.
