I'm a cop in Texas and I support doing away with inspections. Inspections serve little purpose anymore but to inconvenience the law abiding and generate a modicum of income for the state. Inspections, based on my anecdotal opinion, do not improve roadway safety.
The real issue is rampant fictitious 30 day permits, which is what people acquire to avoid having a derelict vehicle inspected. My county of 110,000, with a commuter transient population closer to 150,000, has thousands of fictitious 30 day permits roaming the roads at any given time. With 6-10 Deputies on duty and two additional state troopers, there simply isn't enough time in the day to do anything about it on the street level. The state is trying ways to go after the plate generators online, but its a loosing battle. Lets not even talk about unlicensed drivers...
So in summary, the inspection is pointless as the truly dangerous vehicles would never be inspected anyways.
