Doesn’t require it, it says that it can use GPS data in certain circumstances when there are no road signs.
Case in point, I have had the GPS and the signs say different speeds. For instance several roads here have lately had speed limit changes, the sign detection reads the sign and displays the speed, and the GPS clearly still has the old speed limit. So the speedometer will say 45 and the GPS will say 55, for example. It also always picks up the speed as soon as you pass a speed limit sign.
It also picks up signs that you don’t have in GPS data such as reccomended speeds for curves and off-ramps, etc.

So the VW Touareg. First gen appears to have had those motorized seat belt adjusters as an option on the top end trim

Can we post gas prices in this thread? CL, for a while, had a moratorium on new threads about gas prices, but I'm not sure if we can post them here in this existing thread.
Anyhow, all I wanted to note is that the average price of Tier-1 regular 87 octane in my area (VA-DC suburbs) is now over $5. One Exxon Gas-Mart station hear my house, which is notorious for rip-offs because it is the first station right off a very busy I-66 exit, is charging $5.49 for regular, and $5.99 for premium. Diesel is now $6+
In short, this is just about the highest I can ever remember it, even with short-term bumps after a major storm or hurricane.

With the open-your-wallet gas prices we are all dealing with, here are some quick tips for stretching those not-so-cheap gallons:
....Keep tire pressures up at least to manufacturer-reccomended PSI. Soft tires will not only wear sicker but also produce more rolllng-drag, using more fuel. All else equal, tires will lose about 1 PSI for every drop in air temperature, although the fact that we are heading into summer will help as temps rise. Tire pressures should be checked when cold...after sitting overnight or in the shade for 3 hours. Remember that tires sitting in the sun will heat up rapidly....the black color absorbs a lot of sunlight.
......Clean anything unnecessary out of the trunk or cargo area that adds weight. More weight means the engine works harder....and uses more fuel.
......Avoid downshifting whenever possible, except to keep the engine from lugging or straining. This is equally true for a traditional 3-pedal manual transmission or a manually-shifted automatic.
.......When cruising, cruise in as high a gear and as low an engine RPM as possible to keep the engine from lugging. And slow down....even aero-efficient vehicles use more fuel as cruise-speeds rise.
........Accelerate and brake gently...the more gentle, the better. You will be surprised how much that can affect fuel economy.
.......Try to combine as many trips as possible, so that you are not starting/stopping and continually warming and cooling the engine. Much more fuel is used in warm-ups, because of the richer mixture in the injectors, than with a fully-warm engine.
.........If possible, try to choose routes that have more downhill stretches than upgrades. On upgrades, of course, gravity makes the engine work harder. But don't try to coast downhill in neutral or in too high a gear....that can be dangerous and ruin your brakes, particularly in the mountains, Lower gears help hold the vehicle back on downgrades.

I mostly agree except you should not accelerate slowly, you should accelerate at the engines peak BSFC rpm so you convert the absolute most gas to motion possible. A slow acceleration that takes forever will use more fuel than a quick burst and coasting at desired speed.
Try to avoid braking entirely if possible, it's just wasting energy. If you can coast down from 55 to a stop sign do it.
