Drove all the way to S, Wales & back today & two miles from home i hit standing traffic so i took a detour.
I was following a three vehicles which where making their way passed some parked cars & i heard a crunch.
An old guy (around 75 ish) had just drove into a parked van & car at very low speed that where parked on his side of the road.
Now the van was a good deal wider than the car & so he'd caught the side of the car with his car & ran into the back of the van

I drove passed him & looked down to see a very bemused look on his face whilst he adjusted his glasses (too late mate, should have gone to Spec Savers).
As i drove up the road i saw him get out & walk around to what damage he had just caused.
A prime example of a re-test that should be taken at every ten year intervals to see how competent at driving you are.
