Pretty much, yeah. I race SCCA and build race cars. Exactly why I want nothing to do with these, you don’t own it. You’re leasing the hardware that’s hogtied to the software.

Oh man, you're in for a bad time then, as pretty much everything - yes even amateur racing cars - has software in it now, and you don't own any of it.

As a car guy, it surprises me you weren't aware of this trend yet but I guess we all find out sooner or later. But hey - maybe that '89 Carrera will keep on trucking for a few more decades though - good luck!
