Like some others here, I learned how to drive with auto transmission cars (that's what my parents had). But thanks to some friends who had M/T cars (their own, or their parents' cars), and who were patiently willing to teach me, I became a proponent.
And mentioned in the article, wanting a M/T is NOT primarily about "faster", "better mileage", or "cheaper". It's about the driver being forcibly ENGAGED in the act of driving - you can't turn off your brain while driving stick (no M/T car will ever be autonomous!) It's about the tactile sensation of rowing the gears, feeling each gate, and finding just the right spot in the clutch takeup.
In a nutshell, M/T helps me look forward to the otherwise mundane drives to work, or daycare, or the curling rink in my econobox..because every time I drive the vehicle, I get the simple satisfaction of rowing my own gears while doing it.
As to my part for keeping the M/T alive - ordering a new vehicle (hopefully soon) with a stick. And not a traditional M/T car, like a sports/sporty car - a CUV of some sort. (Part of me is still bummed out about not buying the M/T Mazda5 - how awesome is a M/T minivan!) I'd like to reward a dealership that actually stocks M/T vehicles though - might mean I have to buy from Quebec!
