I think comparing driving drunk with a dive to 132 feet -- or 150 feet -- without helium is a mistake.
It trivializes drunk driving. And, gives an incomplete picture of the vagaries of gas narcosis.
Drunk driving is against the law and carries the possibility of serious fines and imprisonment.
Diving with a great pN2 than 3.1 ata may or may not be wise or desirable; however, it does not carry the sanction of the criminal code.
I think we need another analogy.

I usaly get loaded than drive around town looking for street races to join in on. my cars fast but dont worry if I dont feel right I wont race. Also dont worry because I have been drinking and driving for years now and I know my limits, pluse Ive never killed any one ....at least I dont think I have?

Hey ever notice that the law takes drunk driving far more serious than it takes dangerous sobor driving? It's only a big deal to drive bad if you're drunk. Idiots who always drive bad are more politically correct than drunk drivers wether they drive good or bad.
Wanna bet money that after a six pack that, while I might not be as good as usual, I can still out perform a significant percentage of drivers on the road in any test you want to administer?
I'm with mike in the test group.....now when do we start....

Hey Mike, you say there is no He available in your area? Don't you guys have any gas suppliers out there? What do the welders do?
Setting up a He fill station isn't that big of a deal, especially if you get your tanks topped at a dive store. Some local guys were doing that for a while.

Hey maybe we can find a liquor store that'll sponsor our tests!
A diver getting his on welding helium isn't that big a deal.. getting USP graded helium in many areas is a bigger deal.. if you are a store thats a must. At my station, its policy to analyze all tanks that are marked for other mixtures (also all doubles) prior to filling, if they have a gas other than whats listed on the analysis tag its dumped (if you asked for an air top off thats what you would get), so an Air top off wouldn't fly.. In the end if an accident were to happen it would be the filler that would be in trouble.. if its not analyzed shame on them..
Certainly we have Helium. I pay 80$ for a T? (337 cu ft). I doubt most of the other local shops would top off home brew. I will, but I don't think most will.
No doubt most technical divers have their own fill stations or at least a buddy does. When I first started it was a major deal just to get deco gas for a Lake Michigan dive. If you wanted to get your own tanks filled it would require an extra day hanging around Chicago. Once I had a charter set me up with some 50% for $25 a bottle.
Don't get me wrong, I'm not arguiong in favor of diving narced but I see trimix being used by recreational divers for 100 ft dives a long way off for those who don't mix their own.
BTW, does 40 fathom still have the sign that says that if they top your mix that they charge you for a mix fill?
Hey...we were diving vortex a while back and we were running low on O2. We asked if they had any and they said they had powdered stuff that you just add water too. LOL. Imagine what they would have said if I asked for helium.
