Actually, if you have a smart phone, are the passenger, and don't mind using a little data, you can probably do a search on your phone's browser and come up with the information as you drive. I do it all the time! Occasionally we're in a good area for calls but a lousy area for data, so it doesn't happen, and then I'd write it down.
I also jot down things that I'd like to annotate in my journal that evening. I've transitioned from a hand-written journal to one kept on my laptop (then printed copy later).
