The consensus among the road racers I talked to was that a full face helmet in an airbag car has some dangers. Impact of the airbag into the chin protector can cause hyper extension of the neck by forcing the chin down and back. Open face is the way to go if you have an airbag, but if you don't, a full face is better due to the higher likelihood of collision with a hard object.
I couldn't verify the idea for sure, but it made sense. Plus, I'm extremely hot natured, so the open face is more comfortable. I also found with the full-face loaner that I had to pivot my head down to see the gauges.
and it was cheaper!
The idea is, of course, never to use it for its intended purpose!!
