Can you just leave the bottle open?
I know the answer is no, or there wouldn't be such a market for bottle openers. However, could I just open the bottle before I get in and close it after I get out incase I find that Viper around?
If I'm in and out of the car all day I will leave it open all the time. I just close it when I park the car for the night or if I'm at work. As long as your system doesn't have any leaks you'll be just fine.
