I need more from a helmet

I prefer riding my bike to office than car, for more that one reason.. time, fuel and for the joy of riding the bike. One of the discomfors of riding in the city is inhaling deadly gases from vehicles, many of them are non-compliant to emissions (esp govt buses). I was wondering how to avoid this, then decided to get off the roads and ride through the streets, it works for me in a great deal,but in few jucntions where I cannot avoid getting in to a busy road, and have to inhale those deadly gases. I always wanted to avoid this, I was thinking how gud it would be if I wear a oxygen mask. but it would be great if we have one integerated with the helmet. :). You can refill the oxygen required for 45mins in your helmet and enjoy your drive, wow. If this helmet is equiped with reciving calls on behalf your mobile and play some songs, thats all you would need to put away all your discomforts of riding a bike and make it a pleasant one.
