Oh, this is a fun topic! When I was a kid, my favorite TV show was Knight Rider, Radio Shack was my second home, I impatiently waited at the mailbox every month for the next issue of Popular Science magazine to arrive, and I wrote my own computer software in BASIC. I was always fascinated by cars with lots of buttons and digital displays.
One of the older neighborhood kids with rich parents pulled up beside me while I was riding my bicycle one evening in his mom's new 1986 Buick Riviera. It had the
Graphic Control Center option which was a monochrome CRT with a touchscreen that operated the climate controls, audio system, trip computer, and on-board diagnostics. It also displayed additional gauges. Until then, I had only read about the system and I was absolutely enthralled by it in person. A few years later, Oldsmobile introduced a more sophisticated version called the
Visual Information Center on the 1989 Toronado Trofeo. The VIC with cellular telephone option could be programmed to call a number if the alarm triggered. Those were some of my dream cars, but they would be long gone by the time I could afford one. This was cutting-edge technology in its time, but consumers didn't like it and GM killed it off. It would be years before touchscreens began reappearing and decades before they became mainstream.
Radio Shack would eventually become my first employer when I was old enough to work. I also sold consumer electronics for a while before going to college then owning a computer repair business before becoming an engineer. I've always enjoyed the latest technology and while I appreciate mechanics, I enjoy electronics more.
I spent a lot time growing up around my grandfather, who was a well-respected mechanic that owned his own auto repair shop. He taught me how to work on cars and I was rebuilding starter motors, alternators, and carburetors when I was in elementary school. I was assembling electronic kits before I could properly spell the names of the components.
All that is to say that mechanics, electronics, and cutting-edge technology have been a huge part of my life. I was the first person among my family and friends to own a computer, cellular phone, and now...electric vehicle.
My love affair with lots of buttons began fading when I bought one of the first iPhones. It's hard to believe that was nearly 17 years ago. Since then, touchscreens have become quite common in many different types of products from phones to thermostats to tablets and seem very natural to me.
I like the lack of physical switches that can fail, show signs of wear, and take longer to clean. I like the ability to change the interface through software - this makes fixes and improvements easy. With physical buttons, you're forever stuck with the same design.
I had never driven a Tesla with only one screen before ordering and taking delivery of one, but because it was so similar to "an iPad on wheels", it felt very intuitive. I was concerned that I wouldn't like everything being centrally-located after owning dozens of vehicles with traditional layouts, but I never gave it another thought from the moment I drove it home for the first time.
My vote goes to touchscreens. After having physical buttons for everything in dozens of previous vehicles over the decades, I haven't missed them at all.
