Interesting episode. I have a different feel for radar now and it just doesn't sound intimidating. I may even get the book....well maybe if it's at the library (doubtful), ok maybe used on amazon. Using it in a car makes a lot of sense because as he said you can really accurately define objects in rain, shine, blizzard, sand storm, fog bank, whatever in 3 dimensions. Those are useful characterisitics.
I thought about getting my HAM too but my desire to do so fizzled. I have enough things to do.
The parking pucks are interesting, what happens when I put a faraday cage over a puck? Does a parking droid show up? How long will it take for the protocol to be reverse-engineered? I'll give it a month after public deployment. Or has it already been?
