Computers in Cars

Yesterday I had to take my car in for its annual emissions test. When you buy a new car in Utah, you only need an emissions test every other year until it gets to a certain age. Then you need one every year in order to renew the registration. My car is old enough to require a test annually.

There are a number of places you can go to have the test done. I have a favorite place I have been taking my cars to for decades. They don't do anything other than emissions tests and the state restricts what they can charge for the test. Once the test is completed, the state has an immediate record if it passed or not. When it passes, I can log onto the state website and can see that information, pay the registration fee, and wait for the state to mail me my license-plate decals.

Yesterday I drove to the state test site and waited my turn. I didn't have to get out of my car, I just drove to an open garage door and waited for the car in front of me to complete its test. Then the service technicians waved me into the waiting bay. They connected a cable to my car's OBD-II port and my car's computer gave them all the information. A few minutes later the test completed and I found out I passed. I drove out the back of the garage bay and the guy waiting behind me pulled right in.

I remember buying a new car a couple decades ago and having the salesman tell me that the rapid rise in automobile costs had to do with the addition of new computers. Those computers have helped increase the reliability of most engines. They can tell you when a part has failed and needs to be replaced. They can also tell you how much your car is polluting. It is good that states around the country can tap into that information without any difficulty and help keep our air clean.

I left my house yesterday knowing I needed to get my car's emissions tested. Only twelve minutes later, I returned home with the task completed and ready to submit the results to the state. This is one case where computers have helped create efficiencies in my life. Hopefully you feel the same way.
