As for airplane, there's no electric equivalent to jet engine.
Most modern airliners use high-pass turbofans which produce considerably more fan thrust than jet thrust. The electric equivalent of this is the Electric Ducted Fan jet.
Yellow lights are timed so drivers going the speed limit have at least 1 second to decide whether to stop or proceed through the intersection before they must take action. If drivers get 1 second to decide, shouldn't pedestrians also be given 1 second to decide?
cars...are allowed to be in the intersection when the light changes from red to yellow.
Oops, I meant from yellow to red.
Did you know that your children are more likely to die violently in a rural area than in the city? And people in rural areas are also more likely to die from heart disease and cancer, among other diseases and injuries.
A suburb is a cross between an urban and a rural area, so it isn't clear at all that a suburb is a "much healthier environment" than a city.
Yellow means "Stop if safe to do so" in many places.
In most of the USA, yellow means "the light is about to change to red." But you're right, in a few places it means "stop if safe to do so" which is much more ambiguous, meaning it can be (mis-)interpreted by the wrong jurisdiction to mean things like "stop if you are black".
Here's a bit of trivia: in the USA, drivers have a red phase and a yellow phase, while pedestrians have two red phases (don't cross flashing and don't cross solid). And in Los Angeles, it's illegal to cross while elderly because you can't be in the intersection when it changes from flashing to solid, unlike cars which are allowed to be in the intersection when the light changes from red to yellow. It's madness.
Is it illegal in Chicago to be in the intersection when the light turns red? It's legal in California, as long as your path is clear.
Just launch the aircraft into the upper atmosphere from a railgun catapult built up the side of a mountain. Then it could use electricity generated by the propellers during descent to move the control surfaces.
NASA faked the moon landing, too!
Agreed on all points. +1 if I could.
the vehicle will have different levels of autonomy, depending on how and where it is used.
So it's autonomous except when it isn't.
Wake me when we have a car that's full-time Level 5.
So that they don't have to do validation on the server side? Just do validation on the client side and be done with it?
My company hires many young non-degreed self-taught programmers (because that is all we can find).
Let me guess. You only try to hire people who are looking for a job. Am I right?
The more people, the more cars.
Really? How much are you willing to bet that I cannot name a city with more people but fewer cars than yours? Ha ha!
No amount of careful planning will ever replace dumb luck.
