Depending on the quality of your IT department; it's quite possible that tracking software could be on your work computer and you simply cannot detect it. And yes, corporate tracking can easily detect what you are doing even if you use a VPN. It's best if you simply use work computer for work only. Don't even check gmail on it. Don't even link your google account in your browser.

They wouldn't be doing it if it won't work. Let's face it, the vast majority of consumers will eat this shit up and not bat an eye at the concept. I've been earth long enough to watch products go from 'buy it for life' to today's shit deal of being nickle and dimed for everything. The car subscription model will work and all car manufactures will eventually go the same route; the savvy consumer will eventually no longer have the option to avoid this shit.
