The bus system in Lubbock exists, but students generally take the buses that run solely on campus or the ones that drop people off at certain apartment complexes around town. You need to have a ride to get pretty much anywhere in Lubbock because although it is a small town, it is spread out. If you have the means to have your own car, consider yourself blessed. Lubbock is not the place to try your hand at "going green."
When it comes to the cabs in Lubbock, carry your pepper spray and go with a friend. Safe Ride is a Texas Tech service that provides students with a ride home from anywhere in Lubbock for free with a student ID. This service is open to all students, not just the intoxicated ones. The problem with this service is that the cab drivers who are taking you home don't get paid by you, and therefore they are, for the most part, very rude. You will see cabs around Lubbock, but this is not a city where cabs can be hailed from the street corner. When you are looking to get out of Lubbock or you are picking up a visitor, the airport is less than 10 miles away.
