It is perfectly OK to overtake a slower driver safely and legally, but if you are that impatient you are likely the greater danger.
Kinetic energy has little to do with elderly drivers as far as I am concerned.
My post concerned the inability of many elderly drivers to drive at speeds which are safe for other road users and within the speed limit, which in itself usually has a generous safety margin factored in e.g clear road ahead and no obvious hazards, and that creates a hazard, like it or not.
And I quoted from a source which had nothing to do with my personal driving style, and neither did I mention it.
