Methanol does not act like gas when it comes to that, It is flammable but it does not fume like gas does, There is normally no odor present, You can also vent to the outside of your vehicle, Remember this normally goes under the hot hood with no issues. Now if i was a smoker I would not be running less than 50/50 mix just in case you got in a accident and the tank got damaged and were drenched in methanol, now thats a bad time.

Keeping it at 50/50 keeps it pretty safe.
