I did the math and apparently my car gets about 46 miles per gallon on the highway which is pretty kickass if you ask me , but 17 mpg when using the crazy half - water , half - gasoline concoctions they give you at the gas stations in the middle of nowhere on the 5 . not cool , but whatever . during the drive , I was behind an eighteen - wheeler and one of its tires separated from the tread . it was really frightening and I ended up running over the tread but nothing else happened .

Question with options to choose from: How did the trip end up being ?
Available choices: -- The trip was hard because my car has bad gas mileage .; -- Parts of the trip were dangerous .; -- The trip went off without a hitch .; -- The trip was safe and peaceful .;
Parts of the trip were dangerous .
