Proof that you do save money by driving slower! Finally. Now my husband should stop teasing me and telling me I drive like a grandma. Because, while I do drive like a grandma, its for a good reason.
One of my favorite money blogs, The Simple Dollar, did the math for us. Thanks!
This is why I'm not a fan of the increased speed (75 MPH!) on I-70. I typically go 65 or 70, but feel like people are going to run over me. Anyone else driving under the speed limit on I-70, or elsewhere?
