I'm 60 years old and have been in the car business since I was out of diapers, so I'm familiar with most of the stuff that's been mentioned, from 45 rpm record players and pushbutton transmissions, to vortech intake inserts and various miracle shine products.
Remember when carnauba was an amazing discovery? "Nature's most durable natural armor, harvested from the carnauba palm tree, this wax protects the tree from the extreme heat, humidity and driving rains of tropical forests"! Nowadays, we use carnauba wax as a sacrificial layer over our lab-made sealants!
I hope someday in the future, the same comments we're making today will be made about some of the overdone electronic devices in today's cars. Recently, I had a fellow call me at the dealership in a panic, locked inside his Corvette! Attempting to take it out of winter storage, his first attempt to start it depleted the already-low battery enough that the electric door latches wouldn't function. After reassuring him he didn't have to claw through his convertible top to escape, I explained the location of the manual release handles down by the door sill and he got out. His final comment was "why do we have electric buttons to operate the doors when you still need old-fashioned door handles as a backup?"
For that I had no answer.
