He makes a lot of sounds very, very fast.

On self-driving cars, from Consumer Reports

It's nearly impossible to map all circumstances in all weather conditions. Humans didn't evolve with highly detailed maps in their heads. We can function in places we've never been before because our brains focus only on what they need to know at the moment... You don't have to know everything. -Sheila Nirenberg. Neuroscientist at Cornell.

Before the first ride on a Ninebot One Electric Unicycle

-Charge battery: Red light = effective charging, green light = completed charging
-Place protection foam stickers, (protect the Ninebot One but also your legs in the beginning; place it where your ankles touch the wheel)
-Inflate tires (works at most gas stations without any valve extension) (CST Cheng Shin Tire) says 40-50psi/2.8-3.5bar
-Apply grip tape to foot rests
-install app, check speed limiter
-wear protection, use lights.


Inflating the tyres on the other hand, really is a hassle. Even with the extender it is difficult. For me, personally, it is the only design flaw in this euc. That is to put it politely. You can have a look here:

Thinking outside the box: circular runways

Simple idea. Lots of benefits.
However, if the pilot comes in a little fast and goes over the top of the banked turn, that would be a lot worse than going off the end of the runway.
I'm not sure I buy the environmental benefits - a slightly smaller runway with maybe a shorter taxi distance, but not a huge environmental impact.

cheap helicopter

I ordered a little $100 drone helicopter that uses GPS signals, image recognition to follow someone, sonar sensors to land gently, incredibly detailed 4K video resolution, and gyro stabilization, and runs for 8 minutes. 
The thing is so cheap that many people have gone online to warn people it's such an impossibly low price they can't be real and it's a scam to take people's money. So the company has to keep posting videos to prove that they're real. Here's a video of the manufacturing process. I'm surprised how small the shop is where they are producing these sophisticated devices.
