I don't think you should use it on a road car, at leased not too often. the fumes are highly toxic so whatever you do don't idle using nitromethane. if you do set up a nitro system for your car, let us know with pics and videos.

I know nitro is alot more resistant to knock than gasoline because it withstands 30+psi in top fuel cars. If you just inject it into your car as well as gasoline though, it's not necessarily going to raise the octane rating of your fuel, if you have temps above the ignition temps of gasoline, the gas is going to ignite, then it's going to ignite the nitromethane. it might reduce knock a bit but unless you're running pure nitro, i don't think it will be very much. someone else probably knows alot more about this than me though, so take their word instead of mine.
