Watch it to the end...some scary stuff!!! I'm speechless, do not know what to tell you...sorry.
People are idiots.
There is no course that you have to do before you are "qualified" to drive a mower.
You need no apprenticeship to become a lawn mowing contractor and drive down the road with a truck load of very dangerous weapons.
So you have to learn on the job.
Very few people who actually studied physics at high school understood what they regurgitated in order to pass the exam.
Then you have the effect of radial tyres, ASB , LSD's and disc brakes.
All of these reinforce that the Laws of Motion do not apply to me in the cavity between the ears where a brain should reside.
Sitting on the side of the road you can pick the drivers who cut their teeth on crossply tyres & mechanical brakes.
Futile Government interventions to try & prove Darwin was wrong has prevented idiot morons suffering the penalty of their own stupidity.
Thus every generation the collective knowledge of man kind vastly expands in an inversely proportionally rate to the clowns who ignore it.
