Wheels are replacing the reciprocating kinematics of legs needing at least a pair of legs.

The wheel is a purely human invention nature has failed to produce, whereby the most dramatic break-through was in aviation by replacing the limited-rotation wing joint of birds by an unlimited-rotation bearing to make the pair of wings into a propeller — and yes, a one-bladed propeller or helicopter rotor works perfectly!

Moreover, three-wheeled cars are extremely lightweight constructions thanks to the absence of torsional constraints on the mainframe.

And the only eligible substitute to the motorcar to date is a three-wheeled giro (which will become definitely eligible once it is updated to full VERTOL capacity, i.e. to helicopter technology).

They move pretty danged well….

We have the technology for a House of Representatives with one Rep for every 30,000 to 60,000 population like in the original Constitution. When the cork of 436 was placed on the max rep count at the beginning of the 20th century, we lost our democracy to the corporate power of money. If we had 10,000 Representatives working from their home districts 24/7 electronically instead of being wined and dined in D.C., we would (since now minorities and native Americans can vote – unlike in 1800), have for the first time, a government of the people and by the people. AND 10,000 Representatives is an awful lot of people to bribe, threaten or blackmail. Just sayin’

One Rep per 600,000 population is NOT a Democracy or a Representative Republic, FOR THAT MATTER. :>(

In the same way, our vehicles also has 2 wheels, 4 wheels, 6 wheels and more. So why the 3 wheeled vehicles, even though few vehicles in developing countries have 3 wheels, they are used only in cities.

So please don’t design and try to sell any 3-wheelers.
