Not irony - physics Posted by Ari [Email] (#2847) [Profile/Gallery]

In the 'old days' when most vehicles only drove two wheels, it took some measure of skill to get the car moving. If someone was stuck, it was probably a good indication that for their skill level, zero was their safe speed for conditions. It was an entry level test.
Nowdays there are SUVs and PU trucks with 4WD and all manner of anti-slip and traction control systems. These allow the vehicles to accelerate up a greased slope where the only requirement of the driver is a push on the gas pedal. This elminates that entry level test.
However, since about the 1930's, ALL cars have had 4 wheel braking. 4WD and similar systems don't really improve braking. And SUVs and PU trucks tend to be heavier than sedans, and have higher centers of gravity. Both are negatives when it comes to stopping in a safe manner.
So we've made great strides in going, but not so much in stopping. And not so much in that whole 'keep it on the road' stuff. ABS helps, but once you're sideways, it's a carnival ride. Invariably that feeling of absolute power that a high viewpoint and lots of power driving lots of wheels turns into hubris, and we all know where that leads. People don't lose control of their vehicles, it didn't slip out of their grasp. They didn't have control in the first place, and the first indication that it had left a while back is usually a close-up and personal view of a ditch.
There are no accidents. There is only the certain outcome of physics.
