Sadly, I wonder how many under 30 have even had any exposure to even high school physics, not that those numbers would translate in their minds to traumatic amputations and tissue destroying and bone crushing blunt force trauma.
Far too many have been sold on widget safety: Anti-lock brakes (there are times I want to be able to lock up my brakes!), traction control, airbags, seat belts, crumple zones, and all the features which make cars "safe", all allow people to ignore that the most important safety device in the car is between the driver's ears.
I think somewhere in there the cell phone (immediate one sided blinder), not to mention dinking with 'smart' phones (total loss of focus), music devices, and navigational aids, combined with a general sense of unreality make some oblivious to the consequences of a moment's inattention.
When I drove those old, noisy, drafty vehicles with brakes which worked better when you pumped them, balky manual gearboxes, and no power steering, I had to focus on what I was doing, the road, and drive well ahead to be ready for what was up there by the time I got there. Even in the heyday of the CB radio, we were aware of where we were, and what was going on around us.
Now, it seems the insular environment of a modern vehicle deprives the driver of the real sense of how fast they are going, and what the road conditions really are.
Very similar to many people's conception that because 4-wheel drive gets them going faster in slick conditions, that it also means they can stop faster.
My response is always, "All cars have 4-wheel brakes".
Most people have never handled a vehicle in an adverse situation.
'Avoiding' an accident is a 'lost' skill.
It's just better that they take a nap and let the computer drive.
Only let people who can qualify in a handling test actually drive a car. Utopia is just around the corner. I see Skittles and Unicorns everywhere.
