They do read minds...

I'm now firmly convinced that we have mind-reading computers. In fact, they've been installed in every car that has an "automatic" driver's side window. Thing is, the bugs haven't been worked out... because inevitably, when you want the thing to go right down, it reads your mind, gets it 100% wrong, and stops, requiring you to hold the button down just as though the "automatic" facility didn't exist. Want to open it a crack? It'll dive straight down to China, no matter what you want. This happens invariably, so... trick it! When you want it down, think, "just a little". When you want it part way down, think, "descend, damn you!" :)
