Was (briefly) on an autobahn, at night.. in the tiny A-H Sprite when..
SOMETHING!! went by in the fast-lane (I may have had a guess as to ~what?. but it was er, DARK)

.. at-Least 70 mph faster than our respectable 70ish, sl.rocking our teensy conveyance appropriately..
Loved. It. natch
(Had recently visited Stuttgart/M.Benz re parts for a friend's 300SL) and I touched an SLR! of the '55 LeMans magnesium-conflagration construction.
whereby some guy named Lance ___ Macklin maybe? had cut-off the SLR as ended up immolating n-spectators, self ... while the Perp lost no skin :-/


But I digress.. doubt seriously that our Zooom-passer-by was in something as exotic as That..
But on autobahn.. ya never Know fershure what exotic might be cleaning your clock.

Sorry you missed the two-wheelers :-/ (thus later sketching-in ... all the 3-D vectors of your trajectories :-)
