If you’re driving to Mexico, you will almost certainly want to take the cuotas, or toll roads.  Toll roads charge tolls, which, by Mexican standards, can be substantial.  Please have lots of those pesos you got ahead of time ready.  You may also want to have pesos for emergencies such as paying the mechanic to fix the tire that just blew out or an unexpected stay at a hotel that doesn’t accept credit cards. It’s always good to have pesos with you in Mexico.
