All tests are still remote controlled. None carrying a human pilot. We're already well into 2019. Seems the date to race human carrying craft is rather close when testing is still only half-baked so to speak. Personally, I'd spend a bit more time, for things like safety issues and whatnot - so the sport doesn't get a bad rep just starting out,....or get regulated out of existence. It's not hard to imagine certain scenarios. Whew! All the same, I'll certainly be watching for the outcome.

Racing - well guess there will be someone willing to give it a go, but does seem a perfect way to get yourself badly injured or killed.

Counter rotating rotors make sense if you are getting rid of a tail rotor. These just make the rotors push on air that is running away. Read your Froude equations.

Try tilting the rotors forward to cut down on say 90% of your drag detrimental down force. Sheesh.

How about ducting the rotors? The open rotor design is disaster waiting to happen.

Air racing used to be a thing in the 20s and 30s, before conventional aircraft got too fast to see. Oh, and before people stopped liking sports with really high direct fatalities.

In the meantime there are safer race circuits that put the pilot in a virtual cockpit. Maybe they should do the same with this and not have the pilot in mortal danger.

The main rule no bumping.

Oh, look: More vaporware, er, a "flying car". Y'know, I used to get all mad & stuff that there were no flying cars yet. However, after all my years as a keen observer of the human condition, all I can say is thank god there are no flying cars! Given the general stupidity of the population, these things would be falling out of the sky like freakin' rain. All it'd take is one "hold my beer" moment over a concentration of some hapless folks and...

What could possibly go wrong! ;^) These racing together just isn't going to work slicing and dicing each other up. Now say 3 ducted, tilting units maybe. And more timed against a course alone that direct bumping each other.
