So, how exactly does this work? If I'm flying a real drone, in a real location, then how does your system stop me directly flying into a wall/into some other hazard at high speed?

Is it like a really advanced self driving car with sensors that detect solid objects and automatically steers around them?

Because with that quote from the FAQ, part of me wants to see the result of flying the drone full speed at every solid object in the vicinity. Or see how far it can go before the battery dies...
