Right, but most modern cars have that communication built in, because they use it to update firmware remotely. You can’t turn it off even if you wanted to. Many car companies justify it by saying it is needed to give your location to emergency services if you use their alert button.
If your goal is to roll a 7, then no, weighting one die doesn’t help, because it doesn’t matter which side comes up in the weighted die.
(Another way to look at it is that you can place 1 die on whatever side you like, then roll the 2nd die: you still have a 1/6 chance of rolling a combined 7).
However that is only the case for a 7, because you can roll a 7 with any combination of the first die (and a particular value in the 2nd). If your goal is to roll a 12, then weighting one die towards 6 will affect the odds, because you need a 6 on that first die to roll a 12; any other outcome makes it impossible.
