Human design: what went into deciding how a human-facing thing is made? How did they decide to put the infotainment screen there? Why are BMW dashboard lights orange-ish? Who designs gauges and do they know what they’re doing? What the hell is going on with Mercedes dashes? When will we stop using gearshifts? When will the scourge of the PRNDL knob leave us?
Mechanical design: i.e. why is this car the way it is from an engineering point-of-view? Why is the rear-engine 911 unique, special, and kinda dumb? What makes the BMW M1 a weird BMW and yet perhaps the most special? Why do Ferrari engines catch fire so frequently? Do BMW/Audi/Mercedes design their cars as sedans, coupes, or hatchbacks first?
History: What puts some brands, e.g. Ferrari and Porsche over the others? Is Audi interesting? What is the gestalt of Honda or Toyota? How did the Viper come to have a tractor engine and a Lamborghini body? How does a BMW M car become “the next coming of BMW Jesus?”
Emotion: What makes people think a car is special? What kind of person owns a Koenigsegg or Pagani? Why own a Lamborghini? Is it practical to drive a Ferrari touring car? When does an Acura TL make sense for someone who enjoys cars? What will enthusiast cars look like once electric cars are the norm; will we finally enter a world of boring aerolumps?
…amongst other things. So many questions, so many subjective answers. That’s what makes it fun!
