It might be argued that an individual has already surrendered their expectation of privacy when they choose, under licence, to drive a glass box on public roads.
Expectation of privacy should not be atomic. And under current US law, at least, there's still some expectation of privacy for vehicle operators and passengers. The Fourth Amendment still applies to vehicles; they can't be searched without a warrant, permission, or reasonable cause (which is why the police try so hard to get permission to search when they stop a vehicle not being operated by a wealthy white person).
Or perhaps BB mean that drivers who choose to enter into an agreement with an insurance company to supply said insurer with live data can now do so using this BB system. In which case, their system isn't compromising the driver's privacy, since it is only transmitting data that the customer had agreed to.
Say, do you have a bridge for sale?
BB used to have a pretty good reputation in this regard, back
in the phone days when that was profitable.
Let's stay sceptical. Cynicism is counterproductive.
Cynicism is accurate, to a first approximation.
