There's nothing like a road trip! But it is a long way, so be prepared for that - allow plenty of time, don't rush, and make plenty of rest stops.
Depending on your route you could pass through some of the more dangerous parts of Mexico where drug gang activity continues. Tourists are very, very rarely (if ever) deliberately targeted, but if you stumble into a deal going down it could be bad.
Plan your route carefully.
Mexico has an extensive, good and relatively cheap bus network, and there's a lot of fare competition between internal airlines.
World Nomads went to San Luis Potosi a year back, have a look at this video on staying safe on Mexico's roads.

Hi, i am mexican, from North Mexico.
DONT drive through the North, it is very dangerous! At the moment there is a war between cartels.
There are flights from the US to Leon, Guanajuato ( one hour from San MIguel) Or you can flight to Mexico City and from there, take a bus (from the Airport) to Queretaro and then to San Miguel over 2 years agoAnswered by Valeria via WorldNomads.com
