The act of having a simple GPS-based navigation in a car does not make you trackable over the Internet in any way!
A GPS receiver is simply that: a receiver. It gets the signals from a number of satellites (the constellation has 24 in the system) to figure out its location - using a multi-channel radio. In theory, 6 to 8 to 10 or 12 satellites can be "heard" (depending on your location - whether it is open land or city with skyscrapers), but only four strong signals are needed for a good fix. So, a good 10 channel GPS receiver is sufficient to do an accurate fix. (There are other ways to get better accuracy, but that is beyond the scope of this discussion).
BTW, if the GPS receiver has "way-station" storage, you could use its memory to see where you have been. But that means physical access to the GPS receiver - not over the Internet!
Now, having said all that, you can install systems in your car that do allow remote tracking. There are a number of products on the market for this - many of them use the North American transmission network that my company provides for this exact purpose!
At the present time, (with one exception) these are all add-on after-market products designed for theft recovery, high-value asset tracking, etc. BTW, we are in discussion with some auto OEM's to install these at the factory - this will not happen for at least two to three more years by the way.
The one current exception mentioned above is the GM On-Star system for concierge services. It can report your remote location on demand, but it is my understanding that only their On-Star support people have the ability enabled to locate the car - you cannot do it from the Internet yourself (certainly not at the present time).
