All this engineering is fine, until that sensor, or system breaks down?  These vehicles are becomming so difficult to work on even the dealership mechanics are learning on the the customers&#x27; dime.  I won&#x27;t even get started on the proprietary software, and the fact that independent 3 party repair shops can&#x27;t even buy access to the repair codes.<p>My father used to say I can roll down my own windows.  I thought at the time he was being to hard on the industry. They finally engineered servos that worked longer than a year.<p>He would flip if he saw just how complicated vechicles have become, and how he would wouldn&#x27;t be able to buy a service manual, and do most of repairs. My father bought very few new automobiles, but always bought a factory service manual, and did all his own repairs.  His last vechicle was a 98 Dodge Dakota. It was still simple enough for him to work on, and now myself to work on.  (My father passed away a few years after he bought the Dodge.)<p>I will hand it to certain companies, like Toyota, who engineer complicated vechicles, but these vechicles are putting easily  250,000 miles on the odometer.  Yes, a lot of the fancy features&#x2F;gadgets stop working, but the vechicle still runs, and gets through smog.<p>Needed advances in technology--yes!  Fluff&#x2F;gadgets--no!  But I&#x27;m just an older guy who really never got the need for so many retractable beverage holders.
