Safe Driving

when I drive
I have 360 vision through mirrors
I check blind spots looking over my shoulders
and imagine an elliptical boundary surrounding my vehicle
which alerts my attention should any object enter my extended space

I watch traffic 100 yards in front of me
observing lane change , relative speed between the vehicles and brake use
an ideal speed is a relative 0 to all the cars moving in the same direction
you don't overtake them
they don't overtake you
---for example
as I was going down a hill
when a car pull up behind me
then passed my right
and got ahead of me
then slowed down in front of me
so I slowed down
not wishing to reengage the vehicle

change lanes as little as possible
and change lanes early
