Some of these parts have been more or less unchanged for the entire history of the car, so maybe it's time for a rethink

Modern cars have all sorts of LCD displays in the gauge cluster and in the dashboard, and yet ? It just seems incongruous in the age we live in to have to use an OBD II reader to check for a misfire or catastrophic engine failure.

9.) Floor Mats/Carpeting

When you think about it, carpet really doesn't make a whole lot of sense to be in your car. Sure it looks nice, but why have something in your car that's just going to collect the moisture and crap from your shoes?

There has to be some sort of compromise between functionality and aesthetics.

8.) Tires

Modern tire technology is amazing, but that doesn't change the fact that tires deflate over time and are rendered useless if you drive over, say, a nail. I hope the auto industry invests more in , if for no other reason than .

7.) Sun Visors

Sun visors are great when they work, but their size is pretty limited. I'd be shocked if there isn't a a more clever solution possible, I mean, there has to be.

6.) Suspension

A lot of automakers offer great updates on the old suspension design, like GMs Magnetic Ride Control, but I want to see someone pull a Citroën and rethink the whole thing from the ground up.

If Citroën could develop a hydropneumatic self-leveling suspension in the 1950s, I'd love to see what engineers could come up with today.

5.) Heaters

Some automakers, like Volkswagen, have figured out to integrate an electric heater with an old school design, but I'd love to see the possibility of efficient electric heat explored more.

Maybe it's on my mind because it's the dead of winter, but could you imagine how great instant heat and defrosting would be in the morning?

4.) Dashboards

Digital screens are replacing analog gauges in many modern cars, yet the dashboard design is still really influenced by those old gauges. A lot of automakers have figured out cool ways to use screens, but why not start from scratch and build the dash around the screen?

3.) A-Pillars

Rollover protection in modern cars is much greater than it's ever been, and while that's a good thing no doubt, it totally ruins visibility.

If I were an automaker, especially one that made performance cars, I'd really invest in trying to make thinner A-Pillars that still met modern safety standards.

2.) Car Stereos

Remember when car stereos were swappable? Those days are sadly gone, with touch screens with horrible user interfaces and $2,000 navigation options.

Automakers, if you're going to make us stick with your infotainment, at least make it good.

1.) Camshafts

Camshafts are lovely things for sure, but the possibilities of camless engines with hydraulically actuated . The power, efficiency, and flexibility could make all cars so much better.
