...and it never occurred to you that a hypothetical is just a thinking tool rather than an absolute.
OK, I'll play your game. The car would not turn on after being parked somewhere for four hours. Only an idiot software developer would brick it at high speed on the Autobahn.
That's what FTDI did though. They pushed the malicious bricking driver through an automatic Windows Update to systems already running in production, no? That's pretty much the equivalent of going at high speed on the Autobahn.
I really don't know how Windows' automatic upgrades work, but I would be baffled if an UART driver was updated on-the-fly while it's being used.
If I receive constant 1Mbps stream, the PLL doesn't even have time to stop/start? Or drivers are supposed to handle upgrade hand-off? Sounds crazy complicated, and I don't see the point of such a feature
