This is tough. A very few tobaccos I have been one or two and done. If I'm not really feelin' it, but it's not completely offensive, I'll smoke maybe 5 bowls and then jar up the rest and try again in a couple months, or even a year or two. If it's not a high nic blend, I'll usually just throw it in my pouch and use it for my commutes. I'm usually not too picky about what I smoke while I drive. Normally when I do this, I end up liking the blend by the end of the tin, and wishing I had more.
