If you bought a new car in the last few years, go look in the trunk. There's a real chance the spare tire is gone and a can of goo is sitting where it used to be.
Carmakers made that swap to squeeze out less than a tenth of a mile per gallon. In one year, AAA had to rescue more than 450,000 members who got a flat and had nothing to put on.
Here's how lopsided that trade is. A spare weighs about 30 pounds, and the sealant kit that replaced it weighs about 4. Fuel economy rules grade carmakers on their whole fleet's average, and the Department of Energy's rule of thumb says every 100 pounds costs you about 1% in mileage. So ditching the spare bought around 0.3%. On a car that gets 30 mpg, that's 0.09 mpg.
And the goo only works if the hole is in the tread and the nail is still stuck in the tire. Sidewall cut, blowout, or the nail popped out a mile back on the freeway? You're calling a tow truck. AAA says a refill can cost up to $300, and the stuff expires in 4 to 8 years. By 2017, 28% of new models came without a spare as standard.
Pretty much everything in these photos went the same way. The carmaker saves a few pounds or a few bucks, and you end up paying for it later, usually on the side of the road.
The touchscreen bugs me the most, because what it really costs you is your eyes on the road.
A Swedish car magazine called Vi Bilägare had drivers do four simple things at 68 mph. Turn on the heated seat, bump the temp up two degrees and hit defrost. Find a radio station. Reset the trip meter. Dim the dash. In a 2005 Volvo with regular buttons, all of it took 10 seconds and 306 meters of road. In the worst touchscreen car they tested, the MG Marvel R, it took 44.6 seconds and 1,372 meters. That's most of a mile at highway speed, and every driver got practice time in every car before the test.
So why'd carmakers do it? One sheet of glass replaces dozens of switches, and every one of those switches is its own part number, its own tooling, its own wiring and its own spot in a warehouse. They can also add features later with a software update. It got bad enough that Euro NCAP, Europe's big crash-safety rater, rewrote its 2026 tests so turn signals, wipers, hazards, horn and the SOS button only score if they're physical controls. The Audi Q7 scored 100% on those. The Xpeng X9 scored 20%. A crash-test agency is literally grading buttons back into cars now.
The shifter has the darkest history. Back in 2016, Fiat Chrysler recalled 1.1 million Jeeps, Chargers and 300s over an electronic shifter that snapped back to center after every gear change, which made it hard to tell by feel what gear you were in. NHTSA tied it to hundreds of rollaways. Anton Yelchin's 2015 Grand Cherokee was part of that recall when it rolled down his driveway and killed him.
Those old parts were doing a job nobody ever put on the window sticker. You could use them without looking. A real gear lever tells your hand it's in Park, and a knob clicks two degrees warmer while your eyes stay on the road.
The average new car went for $50,562 last month, and it wants your eyes for stuff a knob handled by feel in 2005.
They really just don't make them how they used to...
