A Tale Of Two Car Design Philosophies

As a classic car enthusiast, my passion revolves around cars with a Made in West Germany stamp somewhere on them, partially because that phrase generally implied a reputation for mechanical honesty and engineering sanity. Air-cooled Volkswagens are my favorites, and in fact I wrote about these, and my own ’72 Super Beetle, almost a decade ago. The platform is incredibly versatile and hackable, not to mention inexpensive and repairable thanks to its design as a practical, affordable car originally meant for German families in the post-war era and which eventually spread worldwide. My other soft-spot is a car that might seem almost diametrically opposed to early VWs in its design philosophy: the Mercedes 300D. While it was a luxury vehicle, expensive and overbuilt in comparison to classic Volkswagens, the engineers’ design choices ultimately earned it a reputation as one of the most reliable cars ever made.

As much as I appreciate these classics, though, there’s almost nothing that could compel me to purchase a modern vehicle from either of these brands. The core reason is that both have essentially abandoned the design philosophies that made them famous in the first place. And while it’s no longer possible to buy anything stamped Made in West Germany for obvious reasons, even a modern car with a VIN starting with a W doesn’t carry that same weight anymore. It more likely marks a vehicle destined for a lease term rather than one meant to be repaired and driven for decades, like my Beetle or my 300D.

Ask Hackaday: Does Your Car Need An Internet Killswitch?

Back in the good old days of carburetors and distributors, the game was all about busting door locks and hotwiring the ignition to boost a car. Technology rose up to combat this, you may remember the immobilizer systems that added a chip to the ignition key without which the vehicle could not be started. But alongside antitheft security advances, modern vehicles gained an array of electronic controls covering everything from the entertainment system to steering and brakes. Combine this with Bluetooth, WiFi, and cellular connectivity — it’s unlikely you can purchase a vehicle today without at least one of these built in — and the attack surface has grown far beyond the physical bounds of bumpers and crumple zones surrounding the driver.

Cyberattackers can now compromise vehicles from the comfort of their own homes. This can range from the mundane, like reading location data from the navigation system to more nefarious exploits capable of putting motorists at risk. It raises the question — what can be done to protect these vehicles from unscrupulous types? How can we give the user ultimate control over who has access to the data network that snakes throughout their vehicle? One possible solution I’m looking at today is the addition of internet killswitches.
