I am a firm believer in using data, facts, and science to prove things, but if it is digital it can be hacked.  So, there definitely needs to be a lot of security to protect and ensure that the data being provided from say a driver-less car has not been tampered with.

It would not surprise me one bit that companies would knowingly falsify data to win a court case, or someone might hack a device to tamper with the data to make a company or individual guilty.
