Your experience with automobile interference is certainly a far cry from
days of old, when we got our first television set (i.e. 1957)...
Every time a Ford would cruise past our house, the picture would get all
staticky, & there'd be a raucous noise coming out of the TV's speaker in
sync with the revving of the engine...!
As kids we'd jump up & look out the window to confirm the make of the
4-wheeled culprit---but after awhile, we'd simply shout out in unison,
"Ford!" until the RFI had thankfully gone up the street...
I guess they never used shielded ignition / spark cables in those vehicles
back in the day...
