Most cars are pretty "hard", electonically speaking.  The ECUs
fitted to Audi turbos since about 1980 have been built in mu-metal cases -
you'd have to hit the vehicle wiring and take out either the flywheel tooth
sonder or the TDC sender - both produce pretty massive signals already and
their cables are shielded.

It's hard to imagine a technology that could do that and not be a danger to
every pacemaker or cochlear implant for several blocks. And what if there's
a hostage in the car?

You could easily demonstrate such a device on a remote airfield.
