hmmm where are we going to get the energy to compress the air, nukes maybe?
Lets bypass the middle man and put a reactor in everyone's caddy, As far as
powering water going vessels we have two time tested, proven methods of
pollution free propulsion. Less is better and in the least popular forms or
aquatic propulsion we have the best.

Maybe getting a bit back on topic ("compressed cars" sounds like a
trip to the auto junkyard), a CA powered wet sub would be a fun thing
to think about. Provided that the CA is clean/oil free it could power
the motor and provide air to the crew. A hookah type system would
allow one to "park" the sub on the bottom and explore a few 10s of
meters from the sub. The CA could also be used to adjust the
buoyancy. Seems less complex than using electric (batteries) for the
motor and CA for the crew.
Also, since the tank could be partially immersed when filling, the
cooling provided by the water would permit faster charging as the
adiabatic heating effect from rapid filling would be somewhat
negated. (Like why scuba tanks are placed in water when
filled...otherwise you get shorted when the air cools and the
pressure drops.)

The government is trying to make electric cars popular, they are a
small minority of vehicles and battery charging technology is simple.
The CA cars would use a complicated/expensive and hard to get
compressor. I just bought one for a gauge calibrator (3000 psi) - low
volume and $6000.
The state and federal governments tax energy sources that are used
for road use and they aggressively enforce the laws. Ask your local
home heating oil dealer if he'd fill your diesel truck's tank. It's
not the grade, the tax is determined by end use.
My guess is that if electric, CA, hydrogen or whatever gets to be
widely used in vehicles it'll get taxed somehow (maybe indirectly via
odometer checks or something like that) and it'll be more expensive
than the same energy source for domestic or industrial applications.
And, if possible, there will be restrictions on where you can
purchase it.

The battery chargers are 120VAC. Why would CA cars be any different?

Some other advantages of compressed air cars? If the car slides down
the boat ramp the engine will still run and the air can be used to
keep the driver alive and inflate the emergency buoyancy bag (could
have used this with that 1950s amphibious car).
Excitement? Imagine a high speed collision between a compressed air
car and a gas powered one.
Anyway, when I think about the possibilities of this French car, I
come back to reality when I realize this is where the Renault came
from.
