Bluster around the advent of self-driving cars has become a constant in the automotive world in recent years. Much is promised by all comers, but real-world results – and customer-ready technologies – remain scarce on the street.
Today, we’ll dive in and take a look at the current state of play. What makes a self-driving car, how close are the main players, and what can we expect to come around the corner?

As the world grapples with the issue of climate change, there’s a huge pressure to move transport away from carbon-based fuels across the board. Whether it’s turning to electric cars for commuting or improving the efficiency of the trucking industry, there’s much work to be done.
It’s a drop in the ocean in comparison, but the world of motorsports has not escaped attention when it comes to cleaning up its act. As a result, many motorsports are beginning to explore the use of alternative fuels in order to reduce their impact on the environment.

Something like 99% of the people on the road at any given moment will consider themselves an above-average driver, something that’s as statistically impossible as it is easily disproven by casual observation. Drivers make all kinds of mistakes, but perhaps none as annoying and avoidable as failure to use their turn signal. This turn signal monitor aims to fix that, through the judicious use of negative feedback.
Apparently, [Mark Radinovic] feels that he has a predisposition against using his turn signal due to the fact that he drives a BMW. To break him of that habit, one that cost him his first BMW, he attached Arduino Nano 33 BLEs to the steering wheel and the turn signal stalk. The IMUs sense the position of each and send that over Bluetooth to an Arduino Uno WiFi. That in turn talks over USB to a Raspberry Pi, which connects to the car’s stereo via Bluetooth to blare an alarm when the steering wheel is turned but the turn signal remains untouched. The video below shows it in use; while it clearly works, there are a lot of situations where it triggers even though a turn signal isn’t really called for — going around a roundabout, for example, or navigating a sinuous approach to a drive-through window.
While [Mark] clearly built this tongue firmly planted in cheek, we can’t help but think there’s a better way — sniffing the car’s CANbus to determine steering angle and turn signal status comes to mind. This great workshop on CANbus sniffing from last year’s Remoticon would be a great place to start if you’d like a more streamlined solution than [Mark]’s.

We’ve featured a lot of car hacks on these pages, most would void the warranty and none of it with explicit factory support. Against that background, Ford’s upcoming Maverick is unique: a major manufacturer has invited owners to unleash their do-it-yourself spirit. It is one of several aspects that led [Jason Torchinsky] of Jalopnik to proclaim The 2022 Ford Maverick Is An Honest, Cheap, Multitool Of A Vehicle And I’m All For It.
There are two primary parts to Ford’s DIY invitation. Inside the cabin are several locations for a dovetail mount called “Ford Integrated Tether System” (FITS). Naturally Ford will be selling their own FITS accessories, but they also expect people to create and 3D-print designs addressing needs unmet by factory kits. CAD files for FITS dimensions are promised, but any maker experienced with a caliper should have little trouble.
Another part of Ford’s DIY invitation is in the cargo area, whose sides were stamped with slots for lumber beams supporting projects like a ~$45 bike rack. There are also threaded bolt holes already in the bed, no drilling or tapping into sheet metal necessary. Behind a few small plastic doors are wires to supply 12 V DC power without the risk of splicing into factory harnesses.
There will always be wild car hacks like turning a sedan into a pickup truck. But it’s great to lower the barrier of entry for milder hacks with these small and very welcome features. QR codes on a sticker takes us to Ford’s collection of video instructions to get things started. Naturally if this idea takes off other people will post many more on their own YouTube channels. We like where Ford wants to go with this, and we would love to see such DIY-friendliness spread across the auto industry. A few Ford videos explaining design intent in this area after the break.

Car keys these days are remarkably complex beasts. Covered in buttons and loaded with security transponders, they often cost hundreds of dollars to replace if you’re unlucky enough to lose them. However, back in the day, keys used to just be keys — a hunk of metal in a mechanical pattern to move some levers and open a door. Thus, you could reshape a wrench into a key for an old car if that was something you really wanted to do.
The concept is simple. Take a 12mm ratcheting wrench, and shape the flat section into a profile matching that of a key for an older car without any electronic security features. The first step is to cut down the shaft, before grinding it down to match the thickness and width of the original key.
The profile of the key is then drawn onto the surface, and a Dremel used with a cutting disc to create the requisite shape. Finally, calipers are used to mark out the channels to allow the key to slide into the keyway, before these are also machined with the rotary tool.
Filing and polishing cleans up the final result to create a shiny, attractive ratchet wrench key. Even better, it does a great job of opening the car, too.
Similar machining techniques can be used to duplicate a key from just a photo (something I did back in 2019 to prank my friend). Alternatively, 3D printing can be great for reproducing even high-security keys. Video after the break.

For almost as long as there have been cars and planes, people have speculated that one day we will all get around in flying cars. They’d allow us to “avoid the traffic” by flying through the air instead of sitting in snarling traffic jams on the ground.
The Klein Vision AirCar hopes to be just such a panacea to our modern traffic woes, serving as a transformable flying car that can both soar through the air and drive on the ground. Let’s take a look at the prototype vehicle’s achievements, and the inherent problems with the underlying flying car concept.
The AirCar is a somewhat futuristic looking, yet simultaneously dated, vehicle. It’s a two-seater with a big bubble canopy for the driver and a single passenger. At the rear, there’s a propeller and twin-boom tail, while the folding wings tuck along either side of the vehicle in “car” mode. At the flick of a switch, the wings fold out and lock in place, while the tail extends further out to the rear. The conversion from driving mode to flight mode takes on the order of a few minutes. The powerplant at the heart of the vehicle is a 160-horsepower BMW engine which switches between driving the wheels and the propeller as needed.
Unlike some concepts we’ve explored in the past, the AirCar has successfully demonstrated itself as a working flying car without incident. Additionally, it did so as a single vehicular package, without removable wings or other such contrivances. On June 28th, 2021, it successfully flew from an airport in Nitra, Slovakia, down to the neighbouring city of Bratislava in 35 minutes – roughly half the time it takes by car. Company founder Stefan Klein was behind the controls, casually driving the vehicle downtown after the successful landing. Continue reading “A New Flying Car Illustrates The Same Old Problems”
All of the technological improvements to vehicles over the past few decades have led to cars and trucks that would seem borderline magical to anyone driving something like a Ford Pinto in the 1970s. Not only are cars much safer due to things like crumple zones, anti-lock brakes, air bags, and compulsory seat belt use, but there’s a wide array of sensors, user interfaces, and computers that also improve the driving experience. At least, until it starts wearing out. The electronic technology in our modern cars can be tricky to replace, but [Aravind] at least was able to replace part of the instrument cluster on his aging (yet still modern) Skoda and improve upon it in the process.
These cars have a recurring problem with the central part of the cluster that includes an LCD display. If replacement parts can even be found, they tend to cost a significant fraction of the value of the car, making them uneconomical for most. [Aravind] found that a 3.5″ color LCD that was already available fit perfectly in the space once the old screen was removed, so from there the next steps were to interface it to the car. These have a CAN bus separated from the main control CAN bus, and the port was easily accessible, so an Arduino with a RTC was obtained to handle the heavy lifting of interfacing with it.
Now, [Aravind] has a new LCD screen in the console that’s fully programmable and potentially longer-lasting than the factory LCD was. There’s also full documentation of the process on the project page as well, for anyone else with a Volkswagen-adjacent car from this era. Either way, it’s a much more economical approach to replacing the module than shelling out the enormous cost of OEM replacement parts. Of course, CAN bus hacks like these are often gateway projects to doing more involved CAN bus projects like turning an entire vehicle into a video game controller.
