I just lay the sucker on its side in the back seat and make sure it can't roll or move around much. I also crack all of the windows.

From my chats with the filling guys, having the tank blow up is less of a concern than the possibility of CO2 filling the car and causing you to pass out. If you start to get a serious headache while driving with the old tank in your car, pull over and get out.

There's a huge, huge difference between a highly flammable NO mix in the trunk that goes boom than a completely non-flammable CO2 tank that, at worse, could have the valve cracked. If that happens, all that will happen is that the tank will take off like a projectile. If you happen to be in the way, then OUCH, but otherwise the vehicle shouldn't end up like this picture.

The biggest risk from compressed gas cylinders is if the stem gets knocked off - as in this demonstration from Mythbusters:
Do not transport cylinders without securing them in some fashion so they can't roll about. Cylinders should be stored in a secured place where they won't accidentally get tipped over, risking shearing off the cylinder stem.

The stem should have a high pressure release valve built into it - which should vent gas if high temperatures result in excessive pressures, preventing explosion of the tank itself.

As an anesthesiologist, I work with compressed gases (oxygen) on a regular basis, and cylinder safety is important...

Look for aluminum cylinders- Often the 20Lb ones will have a safety collar on so if they do get rolled around in the trunk, they should not open.

Heres a photo of what I am talking about
