Letters to the PD and city leaders might make you feel good, but I am sure the PD already knows where these are occurring. As long as BMV is a misdemeanor in Texas, the risk is low, and of course, especially in a college town, the reward is high.
BMV used to be a felony in Texas, but prison overcrowding was a main reason for making it a misdemeanor. Finally, a couple of sessions back, it was changed so that repeat BMV offenders can be charged with the lowest level of felony. But, it seems, the rewards still seem to outweigh the risks, for plenty of burglars.
As for the police, unless there is a surplus of police officers, requests for "extra patrols" are largely a fantasy. I work night shift patrol in another big Texas city, bigger than Austin, and I do very well know where the BMVs are happening. (BMV is THE most common crime in my area; Austin is probably similar.) I drive through those areas frequently, when I have uncommitted time, but generally, the burglars know the hours when I tend to be busy running calls, and they strike at those times, and around shift change. Even though my PD has staggered shift changes, there are periods when there are fewer officer on the street. Moreover, I spend more time patrolling areas where business burglaries occur, because, quite simply, it is the same amount of effort and risk to ME to catch either type of burglar, but a burglar who broke into a building or habitation goes away for years, whereas I will see the usual BMV suspects back out on the streets in days or weeks. Felony arrest look good when the admins tally my productivity, too.
I have arrested, or been present when others arrested, one car burglar FOUR times over a period of years. I recently saw him back out on the street, riding his bicycle at night. A different car burglar I caught inside someone's car was soon back out on the street, and I arrested him a second time shortly after he tried to break into a house. It never ends.
Oh, and by the way, one of my vehicles was burglarized at the POLICE STATION! I had no stereo; nothing fancy, but they got the battery and a small multi-tool. My SUV was parked right by a major entrance, in a well-lit area. I found my battery nearby, beside a disabled car; it did not fit that car. If a police station is not safe, what is?
