I agree! I'd cry my eyes out if my baby had her brains burned out when I was
just innocently driving past a radar station.

Yeah, I agree. I'm amazed at the fuel consumption levels a modern
computer-controlled ignition system and fuel injection system can deliver.
I vividly remember vacations as a child, when we went down to the coast and
my dad had to manually adjust timing on the old Ford we had once we were at
sea level to prevent "pinging" when accelerating. And the joys of Saturday
afternoon carburettor cleaning, blowing out a jet (NEVER use a wire to
clean a jet!) etc. etc.

I wonder... I'm guessing that the RAF radar was a bit more powerful than
you'd get a hand-held "speedcam" like unit to be.
