Isn't 4500 PSI about what we see in SCUBA tanks?
Google says an aluminum 2cu. ft tank holds 80 cu ft @2-3000 PSI
It's about what I have in my Oxygen Cylinder for the Torch when it is full. Those cylinders are machined from a sloid block, and they are heavily regulated. I can only rent them, not own them. You also have to transport them with a heavy metal cap over the valve up top and are required by law to have them fastened securely on trucks. If one of those things got loose, it'd be like a missile.
My trouble with this whole air car thing is that somewhere, there's going to have to be massive compressors working to do this push from atmospheric all the way to 4500 psig. That's going to require a lot of energy, and it's also going to require a colossal set of heat exchangers for that matter.
This reminds me of electric and flywheel cars in lots of ways, because I think in the end all that's bieng done is moving the tailpipe from one place to another.
What's the pressure in a .38spl cartridge?
Yup, and you seen what happened to Jaws.

I would think it would take a hell of a valve to be trustworthy enough to hold back 4500 PSI from blowing your lungs to smithereens. I am no authority on SCUBA but that would be a hell of a lot of pressure.
Actually, it's a bit more. SCUBA tanks typically hold about 3000 PSI, although there are a few that can go up to 4000. Carbon fiber tanks are too bouyant for diving. They are mostly used by firefighters and paintballers.
"Isn't 4500 PSI about what we see in SCUBA tanks?" Yes but most tanks are at 3,000 psi. Just think about the movie Jaws when they shot the scuba tank and blew up the shark. Another car hitting one of these going 70 could have the same results.
