Welcome to the Fitbit Community @happymommy! Your Fitbit Flex may be carrying your steps due to the same error that the clock is not correct. I recommend checking out this article to correct the time. Once you have done that, I'd also try restarting your tracker. You can delete that extra information if needed by manually logging the driving activity.
Keep an eye on it and let me know how it goes.
