Why not low power, safe cars?

I have this sedan from an Indian automaker, and I keep guessing why cars are so powerful. Do we really need so much power and speed on our roads?

If road traffic accidents account for over 1.25 million deaths every year, there is something not right with our commutation systems. Reaching that destination fast is important, but not more important than our life and limbs!

Why don't we make low-power vehicles that don't cross the speed limit of 30 miles per hour (48 kmph) and reduce their horse power to dramatically? We won't do that! On the other hand, we are pulling it up to touch the upper limit!

If we don't want to create a safer world (for the thrill of it), there is again something very wrong with us! Are we civilized at all? Actually, we are living a lie!
