I'm finding it increasingly difficult to avoid purchasing, and therefore tying myself to, 'connected' platforms. I recently decided to purchase a new washing machine. It was difficult to find one that did not feature some form of wireless connectivity. I know from other discussions on this forum around so-called 'smart' televisions[1][2] that simply not connecting the device to your home wi-fi network, or implementing DNS filtering measures such as a PiHole, may not be effective ways to restrict the access of these devices. Not to mention the various security implications of giving these devices access to your network.
The idea of a car having the same connectivity is just a minefield of privacy, security and generally anti-consumer issues. I am not optimistic either that pushback against such concerns will force manufacturers to amend these practices.
