Your thoughts on "Son of Metron".

Fill the trunk with batteries, run two 100 amp alternators in parallel,
solid state batteries switch for the batteries and buy plenty of 0 or 00
stranded wire and expect for a lot more people to hear you then you can
hear ... blah, blah, blah.

Put the extra batteries in series, so you can use some decent
amplifiers requiring 60-100 V. Since it is unlikely that you are going
to transmit all the time, the 12/60 V battery charger inverter can be
rated at a lower power level.

While it may be possible to build mobile antennas that efficiently
radiates most of the transmitter power at VHF/UHF and perhaps on the
upper HF bands, the efficiency of a mobile antenna on the lower HF
bands is very bad, most of the power would be dissipated in the
antenna structures.

On lower HF bands, the car body is not a sufficient ground plane, so
there might be high RF voltages in the car body compared to ground,
which could cause nasty RF-burns if operated on a parking lot and
someone touches the body of the car. Also the modern electronics in
most cars might not work in such environment.
