Onstar equipped cars, (OBD3) all have the ability of being hacked. On a lighter note,
Oregon is testing a GPS computer now, because they claim that Hybrid vehicles aren't paying road use taxes (From the gas pumps). So with that in mind, they are trying to bill drivers BY THE MILE. When you pull up and pump $1.10 gas, it'll be great. Then you'll get a varying monthly bill for the rest. The idea is that Hybrids take up space, and road use just like gasoline cars - And that Semis have had to pay more road tax, and that the system will now work both ways.
When you hit the Oregon line, the GPS stops billing. You'll need the GPS box to authenticate at the pumps to get cheaper gas.
I love my 1981 Toyota.
