Are you comfortable with a new car that has telematics, automatic OTA firmware updates, etc.?

I'm not. As tech person I know how dangerous (from a privacy/safety angle) having a 'connected' vehicle is.

Not only does the car maker get access to the car but so do insurance companies, etc.and this will eventually be used to influence insurance policies, allow governments to control/limit what people can do with their own cars, etc. plus give the car maker carte-blanche ability to force firmware updates.

I'd have a connected car only on one condition - I can locate the radio hardware providing the wireless internet connection and either disable or remove it.
