WARNING - DO NOT LOG ON TO CARS.GOV
If you log on to cars.gov and accept the privacy terms, the government now has the right to take all the information on your computer. That will include all your personal information, bank records, transactions, web site log ins, EVERYTHING ON YOUR COMPUTER.
Cars.gov is the web site set up for the "Cash for Clunkers" rebate program. The site had a poorly written terms of service & privacy statement that was aimed at the dealer support transactions function of the web site. The statement was intended for dealers and their data entry of information on sales made and rebates requested. The statement wasn't aimed at customers and was not related to their use of the web site.
Even if the statement had been intended for everyone, it would not have been legal or enforceable. Recently the "frightening" Privacy Act & Security Statement was updated to have much more accurate and far less disturbing content.
