comment What's the point of the D3 gear in an automatic transmission?
@theUg: This is interesting conjecture, but I still stand by my statement that there will be little if any change. If it completely shuts down the fuel supply, that's likely not much of a difference from the very, very little amount injected if it doesn't. Certainly in my car, it says "MPG is off the charts high" in a higher gear coasting downhill.

comment Remote autostart suggestion
Sure, but it also means that someone with $1 for a key blank and a little time with a file can make a sawtooth key that will open and start your car. Mechanical keys are NOT secure, which is why the industry has been going with immobilizers. Even Medco high-security locks aren't secure because of the mechanics, they're secure largely because the patents on the mechanical tweaks means that they control it so you can't buy blanks (or so says a co-worker who used to be a locksmith).

comment Audi 06 - Replace Thermostat
What exact car is this? I've done some searches for replacement procedures and it doesn't sound too hard, but they are on earlier than 2006. For example, my 2005 S4, with a 4.2L V8 shoe-horned into the same engine bay that normally has a 2.0L engine would probably be much harder, likely requiring removal of the front-end (most work on it does :-).

Note that many "high E" windows in buildings will do a very effective job of blocking RF. I've noticed that some buildings I can't unlock my car through the windows, even if it's right outside.

comment What are the tradeoffs for positive vs. negative ground?
Static electricity such as lightning, at tens of thousands of volts, is likely not a relevant example for what happens in dynamic electricity at the low tens of volts. Though I can't explain why fully. I imagine it has to do with the potential, the positive side of a battery doesn't have high potential relative to earth ground, it has high potential relative to the negative terminal of that same battery. An example of this is that you can't take two batteries and ONLY connect, say, a light bulb to the positive terminal of one and the negative of the other and have it work.

comment How Do I Remove My Socket Wrench Between the Idler Pulley and Wheel Well
Seems like a pipe wrench on the socket would likely work, they are like a crescent wrench but have teeth in the jaws that will grip a pipe when turned one way, and spin free when going the other. Kind of like a socket, but it works by the jaws gripping the round pipe when it spins one direction. It'll likely chew up your socket a fair bit though.

comment How can I be sure my vehicle is a 4x4 / AWD?
Note that this won't work for all AWD systems. For example, a torsen requires there to be SOME friction on both of it's output shafts for it to work, and all 4 wheels may not spin if the front and rear differentials aren't locking differentials...
