Compressed air tanks
One of the most frequently asked questions is about the safety of the compressed air storage tanks. These tanks hold 90 cubic metres of air compressed to 300 bars. Many people ask whether this system is dangerous in case of an accident and if there is a risk of explosion. The answer is NO. Why? Because these are the same tanks used to carry the liquid gas used by buses for public transport. The tanks enjoy the same technology developed to contain natural gas. They are designed and officially approved to carry an explosive product: methane gas.
In the case of a major accident, where the tanks are ruptured, they would not explode since they are not metal. Instead they would crack, as they are made of carbon fibre. An elongated crack would appear in the tank, without exploding, and the air would simply escape, producing a loud but harmless noise. Of course, since this technology is licenced to transport an inflammable and explosive gas (Natural gas), it is perfectly capable inoffensive and non-flammable air.

Compressed air tanks have already been proven safe by one of our partners EADS(AIRBUS). This company's reputation in the aeronautical field is unprecedented, given the reliability of its tanks. What's more, the compressed air does not present any risk of explosion. Countless test have been carried out in the most extreme conditions (gun shoots, resistance to fire...) to guarantee passenger safety in every possible condition. The high pressure tanks have been developed using a similar technology to those used in natural gas vehicles and by firefighters. All are produced with carbon fiber over plastic.
The tanks that MDI puts in its vehicles are similar to those already in use in natural gas busses in Germany and other countries.

Just off the top of my head, I'd say that if you're driving that little cardboard box of a car around at 12mph and you get hit by a semi, your probably not going to live long enough to need to worry about the air tank.

That has more to do with separate infrastructure for commercial transport imo. It'd equalize the playing field in a crash, and shift the burden of taxation from the general public to what does the most damage.
How much will the cars cost?
In Europe the MiniCAT's will be put forward at a base price of 6 .860 Euros (without Iva) except in some options.
The CityCAT's will be put forward at a base price of 9 .460 Euros (without Iva) except in some equipped options. Taxes and subsidized options have not yet been calculated.
