And in an accident it will break into 500 pieces and go 500 feet in every direction.

We have been using compressed natural gas for decades in highway vehicles. The crash test data, and actual crashes, proves your made up claim false.

Carbon fiber tanks designed to withstand 4,000 psi or more are quite strong and don't shatter.

These pieces will go in excess of 500 MPH. I had a 79 Vega that got 35MPG at interstate speed limit. I often stopped to get gas just to stretch my legs and get something to drink. 500 miles in one setting is cruel and usual punishment.

Nope. Hundreds of thousands of these cars are in operation (they are somewhat common in South America, which has plenty of car accidents). It doesn't happen. You can't compare what happens with an enclosed small tank with a six in natural gas feeder line. The auto insurance companies do not charge appreciably more for insuring CNG fueled cars.

At 28 mpg, my Impala is getting 400 + to the tank now.

Really, you think CNG is more dangerous than gas, or any more likely to blow up? I had a friend whose father had a pickup that ran off of Propane and gasoline. You changed tanks by means of a switch mounted on the dash board. It worked great, no problems what so ever. I see no difference between that and a CNG/gasoline fueled vehicle except CNG is most likely much cheaper than propane. I think this is great and much more viable as an alternative fuel than hybrid/electric cars, especially if they put in fueling stations in most areas.
