My radar almost killed a bunch of people

Very, extremely, almost completely unlikely. Digital signaling of any distance uses parity to resolve single bit errors. Also, double bit(or more) errors are usually trapped by a check/sync byte, word, or other validation means(LRC). Which requires a re-drive of the block, or stream. Errors in modern digital signalling is so rare as to be inconsequential. Which is why one can download a video stream to a phone miles from a cell tower, and watch and listen to it without interference. Sometimes, there may be buffering, but bit(s) level errors are a thing of the past.

Edit; there's another stupid math error in the post above! 1000 Internet Points for the first person to find it!

Meanwhile we carry our iphones, or androids in our pockets. The put them on our laps while driving, or most likely hard up against our ears/brain. Keep in mind Steve Jobs and what he perished from.
